Product Description

With a full 103 mm blade, the Nick Williams Gen 5 throttle body unlocks serious airflow potential for LT1 and LT4 performance builds. Cold air flows more freely, throttle response sharpens, and thanks to integrated electronics, control remains seamless. Finished in raw billet or black anodize, it brings a sleek look under the hood while laying the foundation for higher power. Calibration is required, but the result is a confident, precise drive-by-wire upgrade.

Fitment Notes

  • Intended for GM Gen V LT1 and LT4 engines (C7 Corvette, Gen 6 Camaro, etc.) 

  • Requires an aftermarket intake manifold or a modified inlet; does not mount directly to stock manifold.

  • Not compatible with the factory LT1 intake in stock form 

  • Engine calibration / tune is required after installation to function properly
