Product Description

The aFe POWER 92mm Throttle Body (46-39111) is a direct bolt-on throttle body upgrade for a wide range of 2009-2015 GM trucks, SUVs, and performance vehicles equipped with LS-based V8 engines (4.8L, 5.3L, 6.0L, or 6.2L). By replacing the factory 87mm throttle body with a larger 92mm bore, this kit removes a key restriction in the intake tract - allowing the engine to breathe more freely for improved horsepower, torque, and throttle response. Compatible platforms include the Chevrolet Silverado, Suburban, Tahoe, Avalanche, Colorado, Camaro ZL1, and Corvette ZR1; GMC Sierra, Yukon, Savana; Cadillac Escalade, CTS-V; and Hummer H2, H3.

The throttle body features plug-and-play electronics that interface directly with the factory ECU - no tuning, programming, or additional hardware required. An included adapter kit ensures a stable, factory-location fit using all stock mounting points. The upgrade is particularly effective when paired with supporting modifications such as a cold air intake, performance exhaust, or engine tune, where the larger throttle body can deliver its full potential. Simple enough for a straightforward DIY install while delivering real-world performance gains for a variety of builds.
