aFe POWER 76mm Throttle Body

aFe POWER 76mm Throttle Body - Toyota GR86 / Subaru BRZ (2022+)

Maximum Airflow Volume & Sharper Throttle Mapping

Eliminate the final restriction in your intake tract with the aFe POWER 76mm Throttle Body. While the factory throttle body is designed for general commuting, this upgraded unit is engineered for the performance enthusiast. By increasing the bore diameter to a massive 76mm, this throttle body provides a significantly larger volume of air to the intake manifold, allowing your engine to breathe deeper and respond faster. Whether you are naturally aspirated or running a forced induction setup, this is a critical component for maximizing your engine's power potential.

What’s Included in the Box:

- 76mm High-Flow Throttle Body: A brand-new assembly featuring a precision-machined bore.

- Pre-Installed Electronics: Includes the necessary motor and sensors for a true "plug-and-play" installation.

- Direct-Fit Gasket: Ensures a perfect, leak-free seal against the intake manifold.

- Installation Hardware: All required fasteners for a straightforward swap.

The aFe POWER Advantage

- Massive Diameter Increase: Moving from the factory 65mm to a 76mm bore represents a huge increase in airflow capacity, reducing vacuum at wide-open throttle.

- Improved Intake Velocity: The precision-machined internal surface is designed to minimize turbulence, ensuring that air reaches the combustion chamber with maximum velocity.

- True Plug-and-Play: This is not a modified core; it is a complete, new assembly designed to communicate perfectly with your factory ECU and wiring harness without the need for adapters.

- Enhanced Throttle Response: By allowing more air into the manifold with less butterfly valve movement, the "tip-in" response of the engine feels significantly more immediate and aggressive.

- Billet Construction: Built to withstand the high-heat environment of the engine bay while maintaining tight tolerances for consistent idle and performance.

Precision Tip: While this unit is designed to work with the factory ECU calibration, we highly recommend a custom tune to fully take advantage of the increased airflow. When paired with a high-flow intake and the aFe Silver Bullet spacer, this throttle body completes a high-performance induction "trifecta" that significantly transforms the mid-range torque of the FA24 engine.
