FITMENT
- 2011–2015 6.6L Chevrolet Silverado GMC Sierra Duramax LML 2500HD & 3500HD.
DESCRIPTION
Product Overview
-
Pinched intake geometry and bulky silencer boxes throttle the true power potential and responsiveness of 2011–2015 6.6L LML Duramax trucks. The restrictive factory Y-bridge creates severe airflow turbulence right at the intake manifold inlet, choking air delivery, driving up EGTs, and creating noticeable turbo lag under acceleration.
- Unleash your engine’s full breathing capacity with this LML High-Flow Intake Bridge Upgrade. By deleting the restrictive OEM intake resonator and replacing cramped factory plumbing with a smooth, wide-bore airway, it eliminates intake bottlenecks, slashes turbo lag, and keeps your EGTs lower when hauling heavy loads.
Key Features
- Pairs CNC billet flanges with hand-laid TIG welds, pressure-tested to hold a leak-free seal at high boost.
- Unlocks up to 80% more airflow by replacing the intake choke point with a large-radius, mandrel-bent aluminum tube.
- Promotes a cooler, more efficient burn through a jump in air volume and velocity that drops EGTs under load.
- Smoothes the intake path so the turbo spools quicker, minimizing lag and sharpening off-the-line throttle.
FAQ
Q: Why delete the factory resonator at all?
A: The OEM plastic resonator box cracks under constant heat and vibration, causing boost leaks and power loss. A solid aluminum block-off plate kills that failure point, steadies boost, and lets out a clean turbo whistle.
Q: How does the bridge help my EGTs?
A: The restrictive stock elbow starves the cylinders of air and spikes EGTs under load. Opening airflow up to 80% gives you a cooler, more efficient burn — essential for heavy towing.
Q: Can I run this with the factory EGR still active?
A: It physically fits a stock EGR setup, but the EGR keeps feeding in abrasive soot. Pairing this bridge with an EGR delete kit is the ultimate move for max flow with soot-free piping.
Q: What are the warning signs of a failing LML intake elbow?
A: Hairline cracks or failing seals in the plastic resonator show up as power-sapping boost leaks. A solid aluminum upgrade removes those weak points and restores throttle and towing punch.
