FITMENT
- 2020–2022 3.0L Chevrolet Silverado GMC Sierra 1500 LM2 Turbo-Diesel.
DESCRIPTION
Product Overview
-
The 3.0L LM2 Duramax inline-six is widely praised for its incredible fuel economy and smooth power, but its factory EGR system is its Achilles' heel. By design, the EGR redirects hot, dirty soot back into the intake manifold, mixing with oil vapors to form a sticky carbon sludge.
- This sludge restricts airflow, robs you of fuel efficiency, and can cause the fragile, plastic intake manifold to crack over time.
- The LM2 EGR Delete Kit completely removes the EGR valve and cooler assembly. It seals the ports with heavy-duty block-off plates, ensuring your 3.0L engine runs strictly on cold, clean, oxygen-rich fresh air.
Key Features
- Material Construction: Premium T6-6061 Billet Aluminum and Corrosion-Resistant Plates.
- Protects the Intake from Sludge: Completely blocks dry exhaust soot from entering the engine intake, preventing the notorious "soot + oil" carbon buildup.
-
Lowers Coolant & Exhaust Temps: Physically removes the EGR cooler to stop hot exhaust from heating the engine coolant, ensuring lower intake air temperatures.
- Eliminates Cooler Leak Risks: Eliminates the factory EGR cooler—preventing internal cracking failures that dump coolant into the cylinders and cause white smoke or hydrolocking.
- Improves Throttle Response: Feeding your engine 100% fresh air rather than hot, inert exhaust gas restores low-end torque and quickens turbo spool-up.
FAQ
Q: Why is the coolant bypass hose included in the kit?
A: To safely reroute your coolant loop after removing the cooler.The factory EGR cooler has coolant flowing through it. Once removed, the included U-shaped silicone hose bridges this gap, keeping your engine's coolant circulating flawlessly and leak-free.
Q: Is custom tuning required to run this EGR delete?
A: Yes, an ECM flash/tune is required.Removing the EGR valve will trigger a permanent check engine light and put your LM2 engine into a derated "limp mode." You must run a custom delete tune to shut off the EGR software sensors.
Q: Should I pair this EGR Delete Kit with a Turbo-Back DPF Delete Pipe?
A: Yes, for a complete "Full Delete."The EGR delete keeps your intake clean, while the 3" DPF delete pipe opens up exhaust flow. Pairing them allows your 3.0L Duramax to breathe and exhale flawlessly, dropping EGTs and maximizing MPG.
Q: Does deleting the EGR extend the life of my 3.0L Duramax engine?
A: Yes, significantly.By keeping abrasive exhaust soot out of cylinders, engine oil stays cleaner for longer. This reduces friction and wear on vital internal components like piston rings, cylinder walls, and bearings, extending engine's overall lifespan.
