This intake manifolds are designed to maximise performance in highly tuned engines. The fine cast-aluminum intake manifolds allow for large volumes of air to get evenly distributed to all 6 cylinders and achieve the most from larger turbochargers at higher boost levels. It improves mid to high RPM range power. Modifications are required to get this manifold fitted properly. Flange may need to be machined.

It requires to use 1/8NPT fitting for the vacuum port (not included).
