This accessory is a modification package designed for Honda 420 all-terrain vehicles (ATVs). It relocates the air intake and vent lines to a higher position on the machine. This alteration effectively raises the ATV’s wading depth capability, enabling it to traverse deeper water and muddy terrain without water entering critical engine components.
The primary benefit of installing this modification is protection against water ingestion into the engine, transmission, and other vital systems. This is especially important for riders who frequently encounter water crossings or operate in environments with a high potential for submersion. Historically, damage caused by water entering these systems could result in costly repairs or even complete engine failure. The use of this kit mitigates that risk, prolonging the lifespan of the ATV and improving its overall reliability in challenging conditions.
The following discussion will delve into the specific components typically included in such a kit, installation considerations, performance implications, and factors to consider when selecting an appropriate option for a Honda 420 ATV.
1. Air Intake Height
The position of the air intake, elevated by a snorkel kit, is not merely a cosmetic alteration on a Honda 420. It’s a safeguard against the unforgiving elements, a decision that can mean the difference between a successful ride and a stranded machine.
-
Wading Depth Determination
The air intake’s height directly dictates the maximum depth an ATV can safely traverse. A factory-standard intake typically sits low, vulnerable to water ingestion during even shallow crossings. Raising the intake point significantly increases the vehicle’s wading depth, allowing riders to confidently tackle deeper water hazards. For instance, a kit raising the intake by two feet effectively adds two feet of safe wading capacity. However, the highest point should consider the rider’s center of gravity to avoid tipping.
-
Terrain Specificity
The optimal intake height is often dictated by the type of terrain frequently encountered. Riders in areas with consistent deep water crossings require higher intakes than those who primarily navigate muddy trails with occasional shallow puddles. Ignoring this consideration can lead to either insufficient protection or an unnecessarily cumbersome setup. The prudent approach is to assess the prevailing conditions and choose a kit that provides adequate clearance without hindering maneuverability.
-
Impact on Airflow
While elevation is crucial, it is balanced against maintaining optimal airflow. Excessively long or convoluted snorkel setups can restrict air supply to the engine, negatively affecting performance. A well-designed kit prioritizes both height and unrestricted airflow, often incorporating wider diameter tubing or strategic bends to minimize resistance. Consider that horsepower could be sacrificed if the system is not carefully designed.
-
Environmental Considerations
In addition to water, elevated intakes also mitigate the risk of ingesting dust and debris. Raising the intake point away from the ground reduces the amount of particulate matter drawn into the engine, contributing to improved air filter lifespan and reduced engine wear. For example, less frequent filter changes are an economic benefit directly linked to a higher air intake.
The interplay between air intake height and environmental factors defines the capabilities of the modified Honda 420. This crucial aspect of snorkel kit selection underscores the necessity of aligning equipment choices with the intended riding environment. Understanding this correlation leads to better decision-making and enhances the likelihood of successful, uninterrupted off-road adventures.
2. Sealed Connections
The story of a Honda 420 snorkel kit isn’t just about towering stacks and defiant forays into deep water. It is, at its heart, a narrative of safeguardinga tale where sealed connections are the unsung heroes. Imagine the ATV, poised at the edge of a murky pond, its tires gripping the uncertain bank. The engine hums, a promise of power. But that promise is fragile, dependent on a continuous supply of clean air, untainted by the encroaching water. It is at these crucial junctures that sealed connections become paramount. These junctions, where the snorkel’s various components meet, are more than just points of attachment. They are barriers, guardians against the relentless pressure of the water seeking entry. A single compromised seal can undo the entire system, rendering the elevated intake moot and inviting disaster into the very heart of the engine. The consequences are often swift and unforgiving: a sputtering engine, a stalled machine, and a costly tow back to dry land. Thus, the quality of the seals, the tightness of the clamps, and the precision of the fittings become critical variables in this equation. These seemingly small details dictate whether the machine conquers the depths or succumbs to them.
In practical terms, the implications are significant. A rider embarking on a challenging trail in British Columbia, Canada, where creek crossings are frequent and often unpredictable, needs unwavering confidence in the integrity of the snorkel kit’s sealed connections. Each submerged joint is a potential point of failure, a place where water could infiltrate and cripple the ATV. The selection of high-quality materials, such as marine-grade silicone sealant and stainless steel clamps, is not merely a matter of preference; it’s a necessity for mitigating these risks. Proper installation, too, is crucial. A rushed or careless assembly can leave gaps or weaknesses in the system, undermining its ability to withstand the pressures of deep water. Regular inspection and maintenance of these connections are equally important, ensuring that they remain tight and free from corrosion. The use of dielectric grease on electrical connections that are part of the snorkel system (such as sensors) also contributes to the long-term reliability of sealed connections.
Ultimately, the effectiveness of a Honda 420 snorkel kit hinges on the integrity of its sealed connections. They represent the final line of defense against the destructive power of water, and their importance cannot be overstated. The tale serves as a stark reminder that even the most impressive modifications are only as strong as their weakest link. In the world of off-road adventure, where the elements are relentless and the stakes are high, investing in quality sealed connections and meticulous installation is an investment in peace of mind and a guarantee of continued performance, irrespective of terrain or weather conditions. Overcoming challenges requires this attention to detail, establishing a practical foundation for enduring reliability.

The narrative of the Honda 420 snorkel kit is not merely one of design and engineering; it is profoundly intertwined with the selection and application of durable materials. These materials form the backbone of the entire system, enduring the relentless assault of the elements and the punishing demands of off-road use.
-
UV Resistance
The unrelenting sun, beating down on the exposed components of the snorkel kit, poses a significant threat. Plastics can become brittle, paints can fade and crack, and rubber can lose its elasticity. Materials that possess inherent UV resistance, or are treated with UV-resistant coatings, are vital for maintaining the system’s structural integrity and aesthetic appeal over time. Picture a sun-baked trail in Arizona; a substandard material would rapidly degrade, compromising the kit’s functionality and appearance. The implication of failing to consider is short-term use.
-
Impact Resistance
The unforgiving world of off-roading presents numerous opportunities for impacts: stray branches, flying rocks, and the occasional accidental collision. Materials chosen for a snorkel kit must possess sufficient impact resistance to withstand these forces without cracking, shattering, or deforming. A polypropylene pipe that is not properly reinforced could crack when contacted by a tree branch. Therefore, high-impact plastics or reinforced composites are essential for protecting the system from physical damage.
-
Chemical Resistance
ATVs often operate in environments where they are exposed to a variety of chemicals, including gasoline, oil, coolant, and cleaning solvents. The materials used in a snorkel kit must be resistant to these substances to prevent degradation, swelling, or dissolving. A rubber hose that breaks down when contacted by gasoline could cause leaks that could cause the machine to fail. The chemical resistance of the components should exceed the likely chemicals that will come into contact with it.
-
Waterproof Seals
The central mission of a snorkel kit is to protect the engine from water ingestion. The materials used in the seals and connectors must be completely waterproof and capable of maintaining a tight seal under pressure and vibration. Seals made from low-grade rubber can dry out, crack, and lose their ability to prevent water intrusion. The material of the seals must create a proper barrier and it should remain so for an extended period of time.
These are not arbitrary choices. They are fundamental to the longevity and reliability of the entire system. From the heat of the desert to the freezing conditions of a snowy mountain, the materials used in a Honda 420 snorkel kit must stand the test of time and the rigors of the trail, ensuring that the promise of off-road adventure is not cut short by preventable failures. Material science is an integral component of the design process.
4. Proper Venting
Venting, often a silent partner in the overall function of a Honda 420 snorkel kit, is as critical to its success as the more visible intake stacks. Its importance lies not in directing the flow of air into the engine, but rather in managing the breath of the machine its ability to exhale, so to speak. Without proper venting, the carefully elevated air intake becomes a futile gesture, undermined by the pressures building within the ATV’s various systems.
-
Differential Breathers
Differentials, the heart of the ATV’s drivetrain, require venting to equalize pressure changes caused by heat and submersion. These breathers, often overlooked, must be extended along with the air intake to prevent water from being drawn into the differential housing. Imagine a scenario: a Honda 420 plunges into a cold stream after hours of hard riding. The rapid cooling of the differential creates a vacuum, and if the breather is submerged, water will be sucked in, contaminating the gear oil and leading to premature wear or failure. Extending these breathers is as fundamental as elevating the air intake itself.
-
Crankcase Ventilation
The crankcase, where the engine’s lifeblood circulates, also requires venting to release pressure buildup caused by piston movement. The crankcase vent, much like the differential breathers, must be relocated to a high point on the machine to prevent water intrusion. Failure to do so can result in water contaminating the engine oil, leading to catastrophic engine damage. Consider the long-term implications: neglect this small detail, and the substantial investment in the snorkel kit becomes a wasted effort. The consequences of overlooking this venting are high.
-
Fuel Tank Venting
Fuel tanks, too, need to breathe. As fuel is consumed, air must enter the tank to replace the lost volume. The fuel tank vent, therefore, requires elevation to prevent water from entering and diluting the fuel supply. A submerged fuel tank vent can lead to a host of problems, from poor engine performance to complete engine failure. It is a reminder that even the most robust engine will falter if fed with contaminated fuel.
-
Transmission Venting
Similar to the differentials, the transmission also requires venting to regulate pressure fluctuations resulting from heat generation and submersion. Extending the transmission vent line is crucial for safeguarding the transmission’s internal components from water damage. Without this extension, water can infiltrate the transmission, corroding gears and clutches, eventually culminating in a complete transmission breakdown. This preventative measure is essential for ensuring the longevity and dependability of the Honda 420’s transmission system.
The act of properly venting these systems is a subtle yet powerful declaration of foresight, a testament to the understanding that a Honda 420 snorkel kit is more than just a means to conquer deep water. It is a holistic system, where every component, from the towering intake to the humble vent line, plays a vital role in ensuring the machine’s continued health and performance. By attending to these details, the rider transforms the snorkel kit from a mere accessory into a true safeguard, capable of withstanding the rigors of the trail and preserving the life of the machine. These vents are more than just additions to a snorkel kit; they are a necessity.

However, the success of this endeavor hinges not just on the quality of the kit itself, but profoundly on the accuracy of its installation. The components, engineered to safeguard against the elements, become mere ornaments if improperly assembled. A poorly fitted seal, a misaligned tube, a loosely connected clamp; these seemingly minor infractions can transform a protective system into a liability. Water, an insidious adversary, will exploit the smallest vulnerability, bypassing the intended defenses and infiltrating the engine, transmission, or differentials. The consequences can be severe, ranging from degraded performance to catastrophic failure, turning a dream of off-road mastery into a nightmare of mechanical repair.
Consider the case of a Honda 420 owner who, eager to test the limits of a newly installed snorkel kit, ventured into a deep water crossing. Confident in the kit’s reputation, the owner failed to meticulously verify the tightness of each connection. Unbeknownst to the rider, a clamp on one of the vent lines was not fully secured. As the ATV submerged, water seeped past the imperfect seal, slowly filling the differential with a milky, abrasive mixture. The immediate effects were subtle, a slight decrease in performance easily attributed to the challenging terrain. However, over time, the contaminated gear oil accelerated wear on the differential’s internal components. Months later, the differential failed completely, stranding the owner miles from civilization and necessitating a costly and time-consuming repair. This scenario, far from unique, underscores the critical importance of installation accuracy.
The lesson is clear: a Honda 420 snorkel kit is only as effective as its weakest point.

This necessitates a deep understanding of the interplay between the kit’s components and the Honda 420’s specific model, year, and configuration.
-
Model Year Specificity
Honda 420 ATVs, while sharing a common lineage, have undergone subtle yet significant design modifications over the years. Airbox configurations, vent line placements, and even frame geometries can vary between model years. A snorkel kit engineered for a 2010 Honda 420, for example, may not align correctly with the airbox of a 2020 model, leading to improper sealing, restricted airflow, or even physical damage. The importance of verifying model year compatibility cannot be overstated; it is the foundation upon which a successful installation is built. Imagine the frustration of a rider who, after hours of labor, discovers that the snorkel intake clashes with the fuel tank due to a minor frame alteration in a newer model year.
-
Engine Configuration
Even within the same model year, variations in engine configuration can impact snorkel kit compatibility. Certain Honda 420 models may feature different intake manifold designs or fuel injection systems, requiring corresponding adjustments in the snorkel kit’s routing and connection points.

This focus on compatibility enhances the long-term enjoyment and durability of the Honda 420.
7. Filter Protection
The journey of a Honda 420, fitted with a snorkel kit, from dry land to submerged trail is a calculated risk. While the elevated intakes promise safe passage through water, they offer no inherent defense against another omnipresent enemy: particulate matter. Dust, silt, and fine debris, often stirred up by churning tires or lurking in seemingly clear water, pose a silent threat to the engine. The snorkel kit, designed to raise the air intake above the waterline, ironically can amplify the vulnerability if adequate filter protection is not integrated. Without a robust filtration system, the increased airflow facilitated by the snorkel can actually draw in larger quantities of harmful particles, accelerating engine wear and diminishing performance. This cause and effect relationship underscores the critical role filter protection plays within the broader context of a snorkel kit.
Consider the experience of a group of riders traversing a seemingly shallow riverbed in Utah. Their Honda 420s, equipped with snorkel kits but lacking high-quality air filters, encountered an unexpected surge of silt-laden water. While the elevated intakes prevented water ingestion, the compromised air filters allowed fine particles to enter the engine. The immediate consequences were negligible, a slight roughness in engine idle. However, over time, the abrasive silt eroded the cylinder walls and damaged the piston rings, leading to reduced compression and a significant loss of power. This example illustrates that a snorkel kit without effective filter protection is akin to building a dam with a gaping hole; the structure may appear sound, but its ultimate purpose is undermined.
Therefore, the selection of a snorkel kit should never be solely based on the height of the intakes or the perceived robustness of the materials. The quality and type of air filter are paramount. Opting for a high-flow, multi-stage filter, often constructed from oiled foam or pleated cotton, provides a superior barrier against fine particles while maintaining adequate airflow. Regular maintenance, including cleaning and re-oiling the filter, is equally essential for preserving its effectiveness. In conclusion, the symbiotic relationship between the snorkel kit and filter protection determines the longevity and performance of the Honda 420’s engine. Addressing the filter needs when installing the kit is very important.
