GM Duramax LML - Grid Heater Throttle Valve Delete (2011-2016)
Unlock true airflow potential in your 2011â-2016 LML Duramax with this Grid Heater Throttle Valve Delete. The factory throttle valve is a known restriction in the intake tract—especially on tuned or modified trucks. This billet aluminum delete removes the bottleneck, delivering better throttle response, lower EGTs, and smoother airflow where it counts.
Key Features:
- Billet Aluminum Construction: Precision-machined for strength, durability, and heat resistance.
- Improved Airflow: Eliminates a major restriction in the intake system, allowing your turbo to breathe freely.
- O-Ring Seal & Mounting Hardware Included: Everything you need for a clean, secure installation—no extra trips to the parts store.
Why Delete the Throttle Valve?
On stock trucks, the throttle valve helps with emissions-related functions. But once you're tuned or running aftermarket components, it becomes a performance killer. This delete gives you back the airflow your Duramax was designed to move—especially under load or high boost. It’s a simple upgrade with noticeable gains.
