K&N air filter for Duramax Diesel- Yes or No

Jason & Celia-TexasMaster Camper Lifetime Member

This is my first diesel truck so no experience. I have had it for about 6 months, bought used.

I went online to purchase a K&N air filter for my 2020 Duramax and saw a lot of reviews that stated the K&N will cause the engine to throw a air filter error code and that you must first disable the air filter life setting and this will prevent the error code. Secondly, I saw a bunch of others claiming the K&N is not as good as quality paper filters as it lets in too much particulate.

I have always used K&N on my gas truck with no problems.

What are other diesel owners doing? Thanks for any insight.
