K&N air filter for 2020 Duramax Diesel- Yes or No

[Scott_Trailer_Newbe]

When it comes to modern turbo diesels from GMC, Ford and RAM my thinking is the manufacturers spent many millions developing these engines which includes the air intake system. If someone makes a different filter which installs in an otherwise stock air box and claims it is better, I wonder how much they actually spent qualifying that claim. Then in some cases they recommend adding oil to the filter as part of its filtration process. For me it seems best to go with the OEM filter or at least an OEM specification filter.

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.

I have had 3 Dmaxes A 2001, 2011, 2020.
I installed a K&N on my 2001. It was a hassle if you did not get the oiling just right. Too much oil messed up the sensors. too little allowed dust to pass thru. I was able to ge it to work by lightly oilng it, running a few days and repeat the process, after about 6 reoilings it was good. I did not bother with it on my next two trucks. I still have a K&N on my 73 Blazer, but zi just found the diesels too much trouble.
