Plazmaman RB30 SOHC Top-Half Inlet Plenum

This Plazmaman bolt on 'TOP HALF" inlet plenum is designed to suit an RB30 Engine

You must confirm if your engine is using an N/A (RB30E) or Turbo (RB30ET) lower intake runner section. The genuine factory turbo (RB30ET) and N/A (RB30E) runners are different and require a different intake plenum. (A turbo runner plenum will not fit on N/A runners and vice-versa.)

Product Info

There is plenty of clearance with this design to be used in most engine converted vehicles. CNC machined base with hand crafted dome top plenum, internal ram tubes and 5.5L capacity. All professionally Tig welded in house!

Developed to suit all street, strip, drift and high horsepower applications, with a capability of flowing over 800hp. 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 25+hp at the wheels at the same boost pressure. Thanks to the plenum design, air is drawn from all sides of ram tube, meaning the power gain is sustained throughout the entire mid and top end rpm range. The plenum design allows the factory throttle cable, and idle motor to be retained. Included with the plenum is a stud and bolt kit, vacuum fittings and complete fitting instructions.

The best part is, this plenum eliminates the factory crossover piping, meaning shorter intercooler piping and quicker boost response. This upgrade plenum gives the engine bay that ultra clean look.
