    Throttle Body Spacers for Bolt-On Horsepower

    PowerAid Throttle Body Spacers from Airaid are designed to greatly enhance the low-end power and torque characteristics of an engine. PowerAid accomplishes this by spacing the throttle body 1" and adding dyno-proven Helix-style bore(s). As intake air passes through the spacer, the Helix creates vortex action that improves atomization for more complete combustion and efficient-burning engine. The results are better drivability and fuel efficiency.

    All Airaid PowerAid Throttle Body Spacers are manufactured from aircraft-quality 6061-T6 billet aluminum. Each includes all necessary gaskets, hardware, and brackets to maintain proper throttle and cruise control geometry. PowerAid Throttle Bodies can be installed in less than an hour without drilling or cutting. In fact, most are ready to go in only half an hour. A PowerAid Throttle Body is the ultimate intake combination when used with an Airaid Intake System.
