ASEMaster6371 is not correct. The K&N air filter does not void any warranty, in fact GM has a TSB spelling out "the use of an aftermarket oiled washable reuseable filter does not void the warranty". Neither does the intake system. If the failure of a down stream component from the aftermarket component fails as the result of the upstream aftermarket component, that specific failure will not be covered, and shouldn't be. Any aftermarket company with any integrity at all is very supportive of this. All spelled out in the Magnusson-Moss Federal Warranty Act.
All consumers should be aware of this and Technicians especially should be aware of it.
