FITMENT
- 2011–2015 6.6L Chevrolet Silverado GMC Sierra Duramax LML 2500HD & 3500HD.
DESCRIPTION
Product Overview
-
The 2011–2015 6.6L LML Duramax is a legendary powertrain, pulling massive loads with ease. However, because it was built during an era of rapidly tightening emissions standards and strict cabin-noise requirements, GM engineers had to make major sacrifices in under-hood packaging.
- The High-Flow Intake Bridge solves this by replacing these restrictive parts with a wide-diameter, By deleting the weak resonator and smoothing the airflow path, this kit drastically reduces air turbulence, lowers EGTs, and helps turbo spool much faster.
Key Features
- Premium Material: Features CNC-machined billet flanges and hand-crafted TIG welds. Pressure-tested to ensure a leak-free seal under high boost.
- Boosts Airflow by 80%: Replaces the choke point of the stock intake with a wide-diameter, large-radius mandrel-bent aluminum tube, allowing air to flow freely into the engine.
- Lowers EGTs: By significantly increasing intake air volume and velocity, this kit promotes more efficient combustion, dropping EGTs under heavy towing or high-performance conditions.
- Sharpens Throttle Response & Quicker Spool-Up: With a smoother, less restrictive path, your turbocharger builds boost much faster. This minimizes turbo lag and delivers immediate off-the-line torque.
FAQ
Q: What is the main purpose of deleting the factory resonator?
A: The OEM plastic resonator box easily cracks from constant heat and vibration, causing boost leaks and power loss. Deleting it with our solid aluminum block-off plate permanently eliminates this failure point, ensures stable boost pressure, and releases a clean, subtle turbo whistle.
Q: How does this intake bridge help lower my EGTs?
A: The restrictive factory elbow starves cylinders of fresh air, spiking EGTs under load. By boosting airflow by up to 80%, this kit ensures a cooler, more efficient burn—making it an essential upgrade for heavy towing.
Q: Can I install this kit if I still have my factory EGR system active?
A: While this kit physically fits a stock EGR setup, factory EGRs still introduce abrasive soot into your engine. Combining intake bridge with EGR delete is the ultimate setup—maximizing airflow while keeping your new, high-flow piping completely soot-free.
Q: What are the symptoms of a failing factory LML intake elbow?
A: If your stock plastic resonator has hairline cracks or failing seals, you will experience power-robbing boost leaks. Upgrading to our solid aluminum kit permanently eliminates these failure points, restoring your throttle response and towing power.
