Note: First image shows RACE manifold with port injection fuel rail addition. This listing is for STREET manifold with no additional fuel rails.

New release from Process West! The DITTO (Direct Injection Tubular Original) intake manifold offers improved intake aerodynamics allowing for big horsepower potential from stock power levels all the way through to big built engine setups.

Compatible with factory throttle body and EGR systems to allow for true bolt on performance even for emissions controlled vehicles. Also compatible with the Process West Verticooler and Process West Front-Mount Intercooler kits.

The street version of the DITTO intake manifold is for those working within the limitations of the factory direct injection fuel system and are not looking to add additional fuel rails or injectors in the future. For those chasing big horsepower the RACE version features EV14 fuel rail injector bosses and includes matching fuel rails.
