K&N
Who has replaced their stock air filter with a K&N? Are they really better? Improve performance, gas mileage, etc.

That's the biggest problem with them is you have to clean and oil them correctly.d1h wrote:

I did on my 2005 Cummins but the the filters and intakes on the newer trucks flow and last much better than the older ones.- I looked into it for my 2007 2500HD 6.0L
I heard there was alot of issues with Mass Air Flow sensors causing check engines lights. So I passed.
There is plenty of research done on the subject. - Inproper use clogs up the MAS/MAF so NO ot a real good idea.
- If they improved mileage and performance, wouldn't the manufacturer use them?
