ATP Automotive Graywerks 106001 Engine Intake Manifold

ATP's premium replacement GM 3.8l intake manifold is re-engineered to correct common failure points, and importantly, prevent repeat replacements. A metal-cert sleeve is installed in the EGR port, along with a spacer pipe that allows for heat dissipation between the tube and the port. This reduces internal heat build-up and keeps the area around the port cooler, preventing cracks. In addition to this, the manifold is constructed from a heat stabilized nylon, providing better resistance to heat and cold/hot cycles, along with additional reinforcement ribs to further prevent any chances of cracking. The full kit includes a replacement manifold, spacer pipes for early & late production engines, PCV cover, vacuum hose connector and early & late production injector O-rings.
