Duramax LLY upgrades.

Just wondering if anyone has had problems with factory warranties by adding K&N filter or any other upgrades such as the Banks Six Gun Bundle or Edge or any other types.

There is another thread here that covers the issue of aftermarket oiled air filters and warranties...

Regarding aftermarket power products and warranties, the Edge/Attitude (http://www.thedieselpage.com/reviews/attitude.htm) review we did a while back ends with a discussion about "caveats" (how aftermarket products in general affect or can affect your warranty).
