2017-2023 GM/CHEVROLET 6.6L DURAMAX L5P THROTTLE VALVE
Improve throttle response, eliminate restriction, and increase airflow to your 2017–2023 GM/Chevrolet 6.6L Duramax L5P engine with this Throttle Valve Delete (TVD) kit. Designed for off-road and competition use, this high-flow billet aluminum replacement deletes the factory throttle valve, which is known to be a bottleneck in the intake system—especially on tuned or performance-modified trucks.
The factory throttle valve is often used in emissions strategies that may lead to buildup, poor airflow, or boost-related restriction under load. Removing it allows for a consistent, unobstructed path for air into the engine, improving throttle response and overall airflow efficiency.
