DESCRIPTION

Product Overview

• Factory Duramax LMM engines are heavily impacted by stock EGR system issues. Recirculating hot, abrasive exhaust soot back into the air intake causes thick carbon buildup inside the intake runners, degrades engine oil quality, and traps extreme combustion heat—leading to elevated EGTs and potential internal EGR cooler leaks.
  
• The LMM EGR Delete Kit is a direct, budget-friendly solution to eliminate the EGR system. By removing the heavy factory EGR valve and cooler assembly and sealing the ports with precision block-off plates, this essential kit permanently stops soot contamination, eliminates EGR cooler leak risks, and keeps your engine running cooler and cleaner.

Key Features

• Precision CNC Fitment: Billet aluminum and stainless steel plates ensure an exact, leak-free seal on factory LMM intake and exhaust flanges.
  
• Eliminates EGR Cooler Leak Risks: Bypasses the vulnerable factory EGR cooler to prevent internal coolant leaks into the engine cylinder heads.
• Complete EGR Valve & Cooler Removal: Permanently removes the heavy factory EGR valve and cooler assembly, stopping abrasive soot contamination at the source.
• Lowers Operating Temperatures & EGTs: Halts the recirculation of hot exhaust gas into the intake, helping lower overall combustion temperatures under heavy towing loads.

FAQ

Q: Does this egr kit include the 3" intake elbow?

A: No. This is base EGR delete kit that includes only the block-off plates and hardware required to remove the EGR cooler and valve. If you want to upgrade intake bridge, check out egr kit w/intake.

Q: Do I need to block off the factory passenger-side up-pipe riser with this kit?

A: No. Because this kit replaces the factory up-pipe with a riserless high-flow pipe, the EGR branch is completely eliminated—meaning no block-off plate is needed on the up-pipe.

Q: Does installing this kit stop coolant from flowing through where the EGR cooler was?

A: Yes. The included high-temp silicone bypass hose routes coolant safely around the removed EGR cooler back into the engine's primary cooling system, ensuring smooth circulation.

Q: What kind of overall performance gains can I expect after installing this complete master kit?

A: By removing severe intake bottlenecks, eliminating EGR soot, and maximizing exhaust drive pressure, you can expect noticeable throttle response improvements, faster turbo spooling, significantly lower EGTs under load, and a smoother powerband across the entire RPM range.
