Xcessive's bolt on plenum kit for the SR20VE N1 manifold is designed to take advantage of the factory long runner lower section and dramatically increase flow for boosted motors. Featuring a resin base section with 50mm velocity stacks, this plenum kit will substatially increase the runner length. Our two piece runner/plenum design also allows for easier porting and polishing of the intake than standard welded designs.

   The plenum is reversable for use on front wheel drive or rear wheel drive cars where the throttle body needs to face the other direction. You may want our stainless throttle cable bracket. SEE BELOW

   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 set up standard for the Q45 throttle body, but the N1 pattern is also available. (Up to 80 mm bore available and custom bolt patterns as special order, call prior to ordering.)Add $80 for N1 TB pattern.

Stock SR20VE N1 runners not included!! SEE BELOW

Xcessive Manufacturing's SR20VE style IAC remote mount kit (Style 3) is designed to allow the use of stock IAC valve for those who want to maintain as many factory systems as possible on custom intakes. This design with only one air port on the allows it to be welded directly to a plenum if desired, or run remotely with the second hose barb and a length of hose.

  Nissan has multiple IAC/AAC styles, please verify yours before ordering. Be sure your IAC is the one port on the bottom style with the second port as a tube on top.

  The kit comes with the IAC mounting plate and two 3/8" hose barbs. Stock IAC mounting screws are reused as is the stock SR20VE IAC.

  Screws and IAC not included.

Add $40 for welding onto plenum.

This 78* elbow is used to offset the Q45 Throttle Body into a more manageable position and to clear the firewall. This is the recommended part for RWD applications to position the intake tube. Elbow can be rotated for adjustment.
