GM Duramax LML Grid Heater Throttle Valve Delete (2011-2016)

2011-2016 Duramax LML Grid Heater Throttle Valve Delete

Improve airflow on your 2011–2016 Duramax LML with this Grid Heater Throttle Valve Delete. The factory throttle valve can restrict intake flow and limit performance. This upgrade removes that restriction, helping air move more freely for quicker turbo response and more consistent power when you need it.

Performance Benefits:

Made from billet aluminum, this part is built to handle heat, heavy use, and tough working conditions. By opening up the intake system, it helps the turbo spool faster for better throttle response, stronger torque, and smoother driving whether you’re daily driving or towing. It includes an O-ring seal and all needed hardware, so installation is clean and straightforward with no extra parts required.

Why Bother Making This Upgrade?

On stock trucks, that throttle valve is primarily there because of emissions functions. But when your Duramax is tuned or in operation aftermarket parts, that valve becomes a bottleneck. Replacing it with this delete frees up airflow, reducing exhaust gas temperatures (EGTs), and makes your engine run more efficiently and more reliably under boost.

This direct-fit delete does not require modification of the factory unit. Everything is included in the kit, get it installed quick and back in action, whether it's hauling, towing, or simply by having that little bit of responsiveness whenever you step on the pedal.
