This aFe Power throttle body replaces the factory 80mm unit with an 85mm billet aluminum housing, increasing intake air flow for stronger throttle response and added horsepower. The larger, smooth machined bore cuts restriction ahead of the intake manifold, and gains grow as more induction and exhaust upgrades are added. It uses the factory mounting locations and plug and play electronics, so it is a direct bolt-on that requires no tuning.
