This intake collector has been designed to be optimal for tuned engines (400hp to 600hp), with the diameter and length of the intake pipe and the cross-sectional shape of the collector reconsidered. The amount of air flow is improved to distribute air more evenly to each cylinder, improving torque at mid-range. As the amount of air intake is improved between the front and rear cylinders, the difference in exhaust temperature at the turbine inlet between them is reduced, and the air-fuel ratio and ignition timing are optimized to improve power and fuel efficiency. Installation is a bolt-on type that does not require any additional processing (throttle linkage and throttle sensor adjustments are required, however).

This product comes with the "First Generation NISMO Logo Metal Emblem Set."
