Description
Motordyne 5/16″ Plenum Spacer is the original go-to plenum spacer for 350Z and G35 with VQ35DE engine. This is a tried and true spacer that yields power and powerband! Motordyne chose aluminum for the material, so you don’t have to worry about melting. It comes with pre-attached gaskets and is self sealing.
Choose basic for a simple plenum spacer!
Choose IsoThermal to add a thermal barrier to prevent heat soak from motor to the plenum!
Choose IsoThermal Copper if your area gets below freezing to run coolant through a copper spacer for the throttle body.
Installation is simple and suggested power gains are 11-14hp from the spacer kit.
Fits VQ35DE Engine Variants only (single throttle body)
