aFe POWER Throttle Body | 1GR 4.0L & 2GR 3.5L

aFe POWER 76mm Performance Throttle Body Kit

Unlock the full power potential of your Toyota truck or SUV with the aFe POWER 76mm High-Flow Throttle Body Kit. By upgrading the restrictive factory 70mm throttle body to a larger 76mm bore, this premium bolt-on kit significantly increases the volume of clean air entering your intake manifold. The result is instantaneous throttle response, improved mid-range torque, and a noticeable gain in horsepower-performance that becomes even more pronounced as you add additional modifications like exhausts, tuners, or intake systems.

Premium 6061-T6 Billet Aluminum Adapter

At the core of this upgrade is a precision CNC-machined 6061-T6 billet aluminum adapter plate, engineered for lightweight strength and a flawless seal. The adapter features an innovative, integrated Serrated/Swirl combination design. This specialized geometry creates a high-velocity air vortex and intake turbulence just before entering the combustion chamber. This turbulence atomizes the air-fuel mixture more effectively, ensuring a faster, more complete combustion cycle for maximum power delivery.

Technical Installation & Emissions Notes

• ECU Learning Period: Following installation, some vehicles may experience a temporary high idle. This is completely normal behavior as the factory ECU adapts to the massive increase in baseline airflow. The ECU will automatically relearn and smooth out the idle over time; this self-calibration process can take up to 800 miles of driving to complete.
• Emissions Disclaimer: This product is not currently CARB exempt and is not available for purchase in California, or for the use on any vehicle registered with the California Department of Motor Vehicles.
