Intake manifolds are one of the most overlooked modifications on high performance applications or any application for that matter. A properly designed intake manifold will not only enhance air flow but it will also help in the equal distribution of that air to all cylinders, causing a smoother and better performing engine. At EngineLogics we custom make intake manifolds to each customers engine specifications. We have seen incredible results by just changing to a well designed and made intake manifold. Some of our work: Straight Runner Manifold That "Helped" David Lashbrooks 2.0L Turbo Charged MR2 going from 450+ HP to 755 HP.
