The intake manifold spacer for the Nissan VQ35 engine is designed to increase the intake manifold’s volume and reduce the intake air temperature. This results in improved efficiency, greater power output, and enhanced throttle response.
Made from high-quality thermal polymer, the spacer provides excellent insulating properties and installs easily between the factory intake manifold components.
It also helps compensate for imperfect sealing surfaces.
