FITMENT
- 2011-2015 6.6L Chevy GMC Duramax LML 2500 HD 3500 HD Diesel.
DESCRIPTION
Product Overview
- Restrictive intake geometry and continuous soot recirculation limit the breathing efficiency and power potential of Duramax LML trucks. The factory intake bridge creates an unnecessary bottleneck with tight internal passages, while the stock EGR system routes dirty exhaust gases straight back into the intake tract—combining with oil vapors to form power-robbing carbon buildup over time.
- Upgrade your engine's breathing tract with this complete LML High-Flow Intake Bridge & EGR Package. Designed to replace the choked factory air horn and eliminate exhaust gas recirculation, it opens up charge-air flow, prevents engine-robbing intake sludge, and ensures your Duramax receives a steady supply of cool, clean air.
Key Features
- Pairs CNC-machined mounting flanges with the intake manifold for precise alignment and a tight seal that keeps boost from leaking out.
- Streamlines the factory EGR system and cuts soot accumulation inside the intake tract, keeping the air path cleaner for the long run.
- Eases intake restriction and turbulence to smooth out airflow and sharpen turbocharger response when the engine is under load.
- Does away with exhaust gas recirculation so the engine pulls a steadier, cleaner air supply for more consistent combustion.
FAQ
Q: What advantage comes from replacing the stock intake bridge?
A: The stock intake bridge is heavily necked down to clear emissions components, creating a bottleneck right where air enters the engine. Swapping to a high-flow intake elbow bridge increases air volume, smooths out turbulence, and improves boost delivery to the cylinders.
Q: Will this intake elbow withstand high boost pressure without leaking?
A: Yes. The intake bridge features precision CNC-machined flanges and heavy-wall aluminum construction, engineered to withstand high boost pressures without flexing, cracking, or leaking at the manifold interface.
Q: Why pair the high-flow intake bridge with an EGR delete?
A: Installing the intake bridge without deleting the EGR means hot, dirty exhaust soot would still contaminate your new intake. Deleting the EGR at the same time keeps the high-flow bridge completely dry and pure, ensuring airflow performance over the long term.
Q: Does this intake bridge include a port for the factory MAP sensor?
A: Yes. The intake elbow bridge comes pre-drilled and tapped with factory-spec sensor ports (or includes NPT ports for aftermarket boost gauges and N2O injectors), so your OEM MAP sensor bolts on seamlessly with no custom modification.
