New Thermal Intake Manifold 5/8" Plenum Spacer for Infiniti G35 2003-2007 350Z

Thermal Intake Manifold Plenum Spacer for Infiniti G35

This 5/8" thermal intake manifold plenum spacer for Infiniti G35 and 350Z models reduces heat transfer between the intake plenum and the engine, helping keep incoming air cooler for more consistent performance.

Overview

This thermal intake manifold plenum spacer is designed to sit between the upper and lower intake plenum on the VQ35 engine, adding 5/8" of height and a heat-blocking barrier. It helps reduce heat soak into the intake charge, which supports steadier air density and combustion. This thermal intake manifold plenum spacer suits Infiniti G35 and Nissan 350Z owners servicing or tuning their intake system.
