This Plazmaman bolt on inlet plenum is designed to suit Nissans RB25DET R33 Skyline.

There is also enough clearance with this design to be used in most engine converted vehicles. Developed to suit all street, strip, drift and high horsepower applications, with a capability of flowing over 1000hp. By simply bolting this plenum onto the factory runners, and tuning accordingly, expect to see an increase in throttle response, and a power gain of 35+hp. The power gain is sustained throughout the entire mid and top end rpm range. Included with the plenum is a stud and bolt kit.

CNC machined base with hand crafted dome top plenum, internal ram tubes and 4.5L capacity. All professionally Tig welded in house!

The best part is, this plenum eliminates the factory crossover piping, meaning shorter intercooler piping and quicker boost response. Plus, it is much more ergonomically appealing than the factory intake manifold. Our bolt on plenum utilizes the factory throttle cable, factory idle motor and factory throttle body.
