Description

The Motordyne 5/16" ISO-Thermal Plenum Intake Spacer is designed to enhance performance for the Nissan 350Z 2003-2006 with the VQ35DE (non-RevUp) engine. It adds 12-14 horsepower by thermally isolating the upper and lower plenums, reducing heat soak. This spacer is 5/16" thick, providing optimal performance while remaining compatible with the engine cover and strut bar.
