aFe POWER 46-39102 76mm Billet Throttle Body and Adapter Kit for Toyota 4Runner, FJ Cruiser, Tundra and Tacoma

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. 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. 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 76mm throttle body kit uses all factory mounting locations providing stability and a hassle-free installation. All needed hardware is included with the kit. 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). aFe POWER 76mm Throttle Body Toyota 4Runner 10-24/FJ Cruiser 10-14/Tundra 11-14 (1GR-FE Dual VVT-i)/Tacoma 16-23 (2GR-FKS)

Improve airflow, horsepower potential, and throttle response with the aFe POWER 46-39102 76mm Billet Throttle Body and Adapter Kit. Designed to replace the factory 70mm throttle body on select Toyota applications, this direct bolt-on upgrade increases airflow to support improved engine performance. It is compatible with OEM or aFe cold air intake systems, with performance benefits becoming more noticeable as additional engine upgrades are added.

The precision-machined adapter is made from high-strength 6061-T6 billet aluminum for a lightweight, durable construction and precise fit. Its Serrated/Swirl combination design helps create intake turbulence in the combustion chamber, promoting improved fuel breakup and more complete combustion. The kit uses factory mounting locations for reliable fitment and a straightforward installation, while plug-and-play electronics help simplify the connection process. No tuning is required. Some vehicles may experience a temporarily elevated idle while the ECU relearns idle control; this learning process can take up to 800 miles in certain applications.
