Our take on the 2011-2016 LML Duramax EGR Valve Cooler Delete Kit Black Off Plate for GMC Chevrolet

This is an EGR valve and cooler delete kit for the 6.6L Duramax LML diesel in 2011-2016 GMC and Chevrolet trucks. It replaces the EGR valve and cooler with a black off plate and block-off hardware, removing the exhaust recirculation path that soots up the intake and cooler over time. It suits owners doing their own emissions-related work who want a cleaner intake and no coolant-fed EGR cooler to fail. It is not street legal in most US states and needs tuning to keep the check engine light off, which is the main trade-off against leaving the EGR system intact.

Questions and answers

What does this kit actually delete?
It blocks off the EGR valve path and removes the EGR cooler from the exhaust recirculation loop. Exhaust no longer flows back into the intake, so carbon buildup stops.
Will it fit my 2011-2016 Duramax?
It is built for the 6.6L LML Duramax in 2011-2016 GMC and Chevrolet trucks. Check your engine code is LML before ordering.
Will it cause a check engine light?
Yes, in most cases. The ECM expects the EGR system to be present, so you need custom tuning to suppress the codes.
Is it street legal?
No. Removing emissions equipment is illegal for on-road use in most US states. It is intended for off-road and competition vehicles.
Do I need new gaskets or a tuner?
Reuse or replace gaskets as needed, and plan on a tuner to keep the ECM happy. Neither is part of the kit unless the listing says so.
How hard is the install?
It is a DIY job for a confident mechanic, but access to the cooler and valve is tight on the LML. Expect several hours in a garage.
Where is the 2011-2016 LML Duramax EGR Valve Cooler Delete Kit Black Off Plate for GMC Chevrolet cheapest?
