This Plazmaman bolt on inlet plenum is designed to suit Nissan’s 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, and complete fitting instructions.

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, although it’s recommended that you use one of our billet 66mm or 72mm throttle bodies to take full advantage of this plenum. An 85mm Option is also available but this is only recommended for guys who are seeking well over 1000hp and 40 psi of boost – POA

All Plazmaman inlet manifolds and products are precision tig welded by experts in house at our Sydney Facility. Through our ability of manufacturing in house we are able to guarantee these inlets with a life time workmanship warranty. These are rated to 100psi at any RPM level you choose. Plazmaman inlet manifolds utilize some of the most advanced manufacturing techniques. Multi axis HAAS CNC  machines ensure that all the one piece billet bases have tolerances to within .005. The inlet manifold dome utilizes a hard temper 3mm sheet alloy surface that has been made to shape in house utilizing advanced forming techniques.

These manifolds can be supplied in 3 finishes, Raw, Polished, or powercoated Black, for the stealth look.

This manifold is an aftermarket performance product & while it will bolt directly to the factory manifold mounting studs, it will require supporting modifications to install. Some examples of these modifications (but not exclusive to, as every application can be different) are moving, blocking, or re-routing some of the factory coolant hoses & vacuum lines. Relocation of the battery. Throttle cable made to suit your application. Using top feed 14mm o-ring sealed full length injectors. Other lines or fittings may also need to be modified or relocated. This product should be installed by an experienced & fully qualified mechanic.
