Mustang Ecoboost Throttle Body Spacer:

This spacer adds volume to your intake plenum. 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 intake manifold spacer and the gains are tremendous. Over 30 ft lbs of torque on our Focus ST (in using both spacers) and a significant change in the horsepower curve.
