Larger Bore Throttle Body:
This aFe POWER 76mm Throttle Body and adapter kit improves engine air flow over the stock 70mm throttle body. The extra air flow will increase horsepower and throttle response. Performance gains will be more noticeable as more upgrades are added to the vehicle.
6061-T6 Billet Aluminum Adapter:
All adapters are constructed from 6061-T6 billet aluminum and are precision machined for light weight, high strength, and perfect fit and finish. The Serrated/Swirl combination design creates intake turbulence in the combustion chamber which breaks up the fuel creating a more complete combustion cycle increasing horsepower, torque and improving throttle response.
Simple Installation:
This aFe POWER 76mm throttle body kit uses all factory mounting locations providing stability and a hassle-free installation. All needed hardware is included with the kit.
