AAM Competition 350Z Angled Plenum Spacer

The AAM Competition Angled Plenum Spacer is the quickest, easiest horsepower gain available for the 350Z, G35 & FX35 with the N/A VQ35DE. Our unique angled design provides power gains across the board and opens up the upper RPM range considerably.

The billet aluminum spacer sits between the factory upper and lower plenum, creating a larger volume to rush towards the cylinders. You gain 10-15HP in under an hour. 2006 350Z/G35 gain between 6-10hp on average and your engine compartment still looks stock

Installation of the spacer is simple, usually takes less than an hour. The upper plenum is removed, the spacer is dropped right in along with a gasket and the upper plenum is reinstalled with the hardware provided. Spacers for the original strut bar (350Z) are included.
