The Gm service manual says that an over-oiled air filter will damage the MAF and the transmission. It states that dealers should not replace/repair any transmission under warranty coverage in such cases. So I assume that simply installing a K&N filter or aftermarket MAF would void the warranty.

 

just keep your factory parts to the side and if there are any questions in the back of your mind, just swap them back on when you go in for warranty work.

 

Its kinda hard to swap out a RADIX before you go in for service

 

how will a airfilter hurt your tranny??

 

It's all up to the dealer as they have final say.

Any part that has the potential to increase power levels beyond stock could be enough justification for a denial of warranty work.

However nothing will COMPLETELY void your warranty, only certain portions of it. Your installation of an air filter should not void your electrical warranty, drivetrain quite possibly.

Let's put it this way, you have to pay to play. If you are the type to cheat the system and make it harder for all of us to come in with legitimate issues, then you should die in a fiery crash. Or at least be hung by your pubic hairs in public.

 

 

Damn near everything will void your warranty at many dealers. Cat-back exhaust is the only thing I haven't seen them complain about.

 

There was a service bulletin a couple years ago about people installing K&N filters with too much oil on them. What was happening was that oil was coating the MAF sensor and screwing up the readings. One of the side-effects was that it would mis-calculate engine load, which will effect the shifting of the trans and the associated line pressures.

A friend of mine took his duramax to the dealer because it was running like crap. When they pulled the MAF, it was coated with oil and even cotton sucked of the K&N, and his was oiled right from K&N and installed new. It can happen.

oh ok

 

I just cleaned and re-oiled mine a few weeks ago and it's running fine. I might take it off and spray some contact cleaner on the maf wires anyway.

My dealership said a mod could void a portion of the warranty.
