Nismo Intake Collector (Manifold) Kit - RB26DETT

To get the most efficient shape for tuning engines 400hp to 600hp, the diameter & length of the intake pipe and the shape of the intake collector's cross section were redesigned. This improved air distribution to each tube, as well as equalizing the air flow volume to each side, increases torque in the mid-rpm range. Fuller air intake to both the front and rear reduces the difference in air temperature on both sides of the turbo. This optimizes the air-fuel ratio and ignition timing, which increases output and improves fuel consumption. Simple bolt-on installation means that no additional work is required, however the throttle linkage and throttle sensor must be adjusted.
-Intake temperature difference at the entrance of turbo chargers is improved an average by 18% in the 2,400 to 7,600 rpm range
- At 4,800 to 7,600 rpm, power output is increased by an average of 1.8%, while fuel economy is improved by an average of 0.4%
