Product Description

The Weistec M177 Intake Manifolds feature a cast aluminum construction for increased strength, when compared to OEM plastic manifolds. Engineered and designed with increased plenum volume to support better flow and significantly higher power levels. The manifolds install directly in place of the OEM plastic manifolds making them ideal replacements for broken OEM manifolds, as well as a supporting upgrade for those looking to maximize the horsepower of their vehicle. Our manifolds are manufactured to allow port injection to meet the high fuel demands of large turbos and high ethanol content fuels. For those that do not want to run port injection, the manifolds include plugs and brackets to seal off the injector ports. Each manifold also has a 1/8" NPT port that can be used as boost/vacuum reference points while also retaining all ports for OEM sensors and emissions connections.
