-SR20VE Bolt on Plenum Kit (P12 round port)

Xcessive's bolt on plenum kit for the SR20VE 20V (P12 oval port) motor is designed to take advantage of the factory short runner lower section and dramatically increase flow for boosted motors. With a  smoothed radius on the plenum adapter plate and significant increase in plenum volume, air flow will be dramatically increased in the upper RPM. Our two piece runner/plenum design also allows for easier porting and polishing of the intake than standard welded designs.

   The runners are shown with the plenum set up for a rear wheel drive application, the plenum is reversible for use on front wheel drive cars where the throttle body needs to face the other direction. If your running a stock throttle body on a front wheel drive application, you may want our stainless throttle cable bracket, click here.

   The new plenum is permanent mold cast for superior finish and casting soundness with a phenolic shell core used for internal walls to yield some of the best quality available. The plenum is drilled for the factory throttle body and bolt pattern but comes pre machined for up to a 70 mm bore (Up to 80 mm bore available and custom bolt patterns as special order, call prior to ordering.)
