RB25 – R34 NEO Inlet Plenum

Description

Based on the highly successful R33 design, we knew that there was no need to reinvent the wheel, so created a plenum to suit the R34 NEO engine as well… Suits all street and high horsepower applications CNC machined base with hand crafted dome top plenum, internal ram tubes and 5.5L capacity Uses factory cable, battery and idle speed motor. Throttle body must be changed to a Plazmaman billet item, due to the OEM physical size (and ugliness!) 66mm or 72mm for street use recommended for applications of up to 900hp. The factory fuel pressure regulator must be also replaced.
