Boomba Racing Intake Manifold Spacer-Ford Focus RS / Focus ST / Mustang Ecoboost
This spacer adds volume to the air entering your head. This has been shown to aide in cylinder filling at lower RPM, smooth out throttle response, build boost sooner, and lengthen the effective wave pulse of the intake charge.
The spacer also includes 8 1/8" NPT threaded ports that can be used for aftermarket injection set-ups such as Aquamist. They come with plugs for those just wanting to use the spacer on its own.
