This is the Process West DITTO FA Intake Manifold. DITTO stands for Direct Injection Tubular Original, and this intake manifold has been designed utilizing a billet aluminum plenum that provides more volumetric efficiency, and it is ideal for those of you looking for a proper intake manifold that can handle more power and boost. The factory intake manifold is made using plastic construction, and although it is an effective factory design that can handle bolt-ons, it can be a limiting factor in terms of flow for those of you with larger turbocharger builds making more power that will greatly surpass the limits of the factory intake manifold. 

This intake manifold will come in a polished billet finish, and although it has been engineered to perform, it will also greatly improve the overall engine bay aesthetics. A great investment for those with weekend show cars, and very effective for enthusiasts with a track-dedicated race car or rally car.
