Intake Manifolds

A generic image

Increasing horsepower while maintaining a punchy bottom end is a priority for rally cars and is especially helpful on the street. Dyno testing has proven that even mild normally aspirated engines gain as much as 12% after this simple bolt on with next to zero reductions in low-rpm torque. Engines running boost, head work, wild cams, etc. will benefit even more. The aggressive growl sounds simliar to anyone who has heard ITBs in action.
