Careful with 2021 L5P read before buying
Installed in my 2021 L5P and it has not been a good start. I checked and everything is tight, but the truck has thrown a few codes and I had to disable the sensor for the filter life. I’m honestly considering going back to a factory filter, but these are great. GM is the problem.If you have a 2021 L5P and you have issues after installing one of these “I told ya so”. It seems ok now, but I reset all modules in the ECU. Not everyone can do that.

NOT Good for the new Duramax
This will probably trip an error message on your Driver Information Center that has to be cleared at the dealer. DO NOT USE! Sent emails to K & N and got no response. Poor customer service!

Read before buy

DO NOT order for L5P Duramax Diesels!!!!
Product DOES NOT work with L5P Duramax 6.6 Diesel Engine!!!! Causes Air Filter and ECM codes that require DEALER to clear. I should have paid closer attention to reviews and stuck with paper filters. I’ve used K&N filters on all my vehicles for decades and never had this issue before. Definitely disappointed.
