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

Unlock improved airflow for your 2011–2016 LML Duramax with this precision-engineered Grid Heater Throttle Valve Delete Kit. The factory throttle valve is a common airflow restriction, especially noticeable on tuned or modified trucks. Crafted from billet aluminum, this delete eliminates that bottleneck to deliver enhanced throttle response, lower exhaust gas temperatures (EGTs), and smoother intake airflow where it matters most.

Key Features:

• Billet Aluminum Construction: Precision-machined for superior strength, durability, and resistance to heat.

• Improved Airflow: Removes a key restriction in the intake tract, allowing your turbocharger to perform at its full potential.

• Complete Installation Kit: Includes O-ring seals and all necessary mounting hardware for a clean, secure fit—no extra parts needed.

Why Remove the Throttle Valve?

While the factory throttle valve plays a role in emissions control on stock trucks, it becomes a performance limiter once you’re running tunes or aftermarket components. This delete restores the airflow your Duramax engine was designed for, especially under load and high boost conditions, resulting in noticeable performance gains.

Compatibility:

• 2011–2016 GMC Sierra 2500HD/3500HD with 6.6L Duramax LML engine

• 2011–2016 Chevy Silverado 2500HD/3500HD with 6.6L Duramax LML engine
