aFe Power offers throttle bodies for a variety of applications, including many Toyota vehicles from 2003 and up. Product details (model 46-39103): * Brand new 76mm throttle body * No tuning required * Plug-n-play electronics * Billet aluminum adapter * More power and better throttle response * Hardware and gasket included * Direct bolt-on for simple installation * Larger bore throttle body: This aFe Power 76mm throttle body and adapter kit improves engine airflow over the stock 65mm throttle body. The extra airflow will increase horsepower and throttle response. This kit will work with OEM or aFe cold air intakes. 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: Throttle body kit uses all factory mounting locations, providing stability and a hassle-free installation. All needed hardware is included with the kit. * Installation note: Idle will run high on some vehicles but will readjust once the ECU learns to properly control the idle (this can take up to 800 miles on some vehicles).

These JET Powr-Flo throttle body spacers use aerospace engineering combined with years of experience. The exceptional design of the bore causes the incoming airflow to actually smooth out and speed up. This creates a type of compacted air-charge that enters through the throttle body and builds pressure in the combustion chamber. This will result in an extensive gain in the midrange power band and an overall increase in fuel economy.
