aFe 13-20 Subaru BRZ/Scion FR-S 70mm Throttle Body - 46-39106

This aFe POWER 70mm Throttle Body and adapter kit improves engine air flow over the stock 65mm 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.

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. This aFe POWER 70mm throttle body kit uses all factory mounting locations providing stability and a hassle-free installation.

All needed hardware is included with the kit. It is recommended to install this throttle body kit with an aFe cold air intake.
