R33 Nismo Intake Collector Hose-Vac Clutch Booster

To find the most suitable shape for tuning engines (400ps to 600ps), the diameter and the length of the intake pipe, and the cross section shape of the intake collector was redesigned. The distribution of air to each tube was improved to provide more equal airflow volume, improving torque in the mid-speed range. Improved air intake volume between the pipes of the front and rear sides reduces the difference in air intake temperature on both sides of the turbine, optimizing the air-fuel ratio and ignition timing and providing increased output and fuel consumption. Simple bolt-on installation means that no additional work is required!
