Engineered to equalize flow and improve efficiency, this precision cast-Aluminum surge tank was designed for maximum performance. It was developed and manufactured in Japan and has been proven on the track with the 200+mph GReddy 35RX GT-R, as well as in the USA with the 8.79sec Quarter-mile SP Engineering/HDM GT-R.
The carefully computer-modeled RX INTAKE MANIFOLD features an optimized 3-piece design with large 58mm diameter runners (OEM 56mm,) with integral velocity stacks for the center section. It has a symmetrical Left and Right surge tanks that are 85% larger then the factory Nissan VR38 intake manifold. The improved design routes air-flow more evenly to each cylinder (which is very important when trying to safely extract the most power from a high horsepower application.)
The RX INTAKE MANIFOLD is also compatible with both the factory throttle bodies or the new big bore, billet GReddy RX Throttle Kit
