Made from premium billet aluminum, Boomba Racing is excited to announce our Intake Manifold Spacers for the Fiesta ST! 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. In the picture shown above, you can see the dyno charts of this spacer paired with our throttle body spacer and the gains are tremendous. Over 17 ft lbs of torque on our Fiesta ST (in using both spacers) and a significant change in the horsepower curve. The spacer also includes 8 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. -All hardware is included (corrosion resistant) -Comes with engine cover stud relocation kit (allows you to use stock engine cover) -Smooths air entering the cylinders -Does not require a re-tune -Greatly increases throttle response -Improves MPG -Build boost earlier
