Cosworth Intake Manifold (EJ257)
[ Currently Out of Production as of 11/9/23 ]
Roger Clark Motorsport has worked with Cosworth to get them to make a brand new run of their High Volume Intake Manifolds for the EJ257 engine!
The Cosworth Subaru High Volume Inlet Manifold is cast from aluminium featuring large tapered runners with radiused inlets for improved air flow. Plenum volume has been substantially increased and tuned for power. Engineered for easy installation and is the key to making big power. The Cosworth EJ257 plenum is designed for use with the 2004-2009 STI engines equipped with electronic throttle control.
The Cosworth High Volume Inlet Manifold replaces the factory Subaru plenum in vehicles equipped with an aftermarket front-mounted intercooler (FMIC) kit. Throttle body position remains stock, ensuring fitment with any brand FMIC kit designed for the stock throttle body and intake manifold.
