aFe POWER 76mm Billet Throttle Body for Select 2010-2024 Toyota 4Runner/Tacoma/Tundra (V6-4.0L) 46-39102

Fits select 2010-2024 Toyota 4Runner, FJ Cruiser, Tacoma, and Tundra models (V6-4.0L).

The aFe POWER 76mm Billet Throttle Body is a direct-fit performance upgrade designed to replace the restrictive factory 70mm unit. By increasing the bore diameter to 76mm, this kit significantly enhances airflow to the intake manifold, improving throttle response and providing additional overhead for vehicles with existing bolt-on modifications. It is fully compatible with both OEM and aFe POWER cold air intake systems.

This kit features a precision-machined 6061-T6 billet aluminum adapter with a unique Serrated/Swirl combination design. This internal geometry creates intake turbulence within the combustion chamber, promoting a more complete air-fuel mixture for optimized combustion. The plug-and-play electronics require no harness modification or aftermarket tuning, and the unit bolts directly to factory mounting locations for a straightforward installation.
