This modification for the Datsun 280z involves replacing the factory air intake system with one designed to draw cooler air into the engine. The goal is to reduce the temperature of the air entering the combustion chamber, as cooler air is denser and contains more oxygen per unit volume. This increased oxygen can lead to a more efficient combustion process.
Employing a system that delivers cooler air can yield improvements in engine performance, including increased horsepower and torque. These enhancements are often most noticeable at higher engine speeds. Historically, enthusiasts have sought methods to improve the 280z’s output, making aftermarket air intake systems a popular upgrade. The design and materials used in these systems play a critical role in their effectiveness and durability.
