Product Details

Building an engine to be capable of extreme power requires a large amount of air to be able to make it's way into the combustion chamber. Even with increased cylinder heads, cams, valves, etc. you can only pull in what the manifold will allow. If it's time to upgrade your intake manifold and the only option is perfection, Cosworth high volume manifold meets your requirements.

Cosworth High Volume Inlet Manifold is cast from aluminum featuring large tapered runners with radius inlets for improved air flow creating a substantial increase of Plenum volume significantly increasing power capabilities. These have been engineered for easy installation and feature an integrated vacuum manifold with connections for your brake booster, boost gauge, MAP sensor, etc.

This manifold is designed for the EJ257 with STI engines fitted with electronic throttle control and is not designed for use with any cable-actuated throttle body EJ20/25 applications. Cosworth manifold has been dynamically built to be compatible with standard or forward mounting throttle body configurations handy by maintaining the stock throttle body location, this manifold will be compatible with most aftermarket front mount intercooler kits.
