This bulletin is being revised to add models and model years. Please discard Corporate Bulletin Number 04-07-30-013A (Section 07— Transmission/Transaxle).

First, Inspect the vehicle for a reusable aftermarket excessively/over- oiled air filter

DO NOT repair MAF sensors under warranty if concerns result from the use of an excessively/over-oiled aftermarket, reusable air filter.

The use of an excessively/over-oiled aftermarket, reusable air filter may result in:

• Service Engine Soon (SES) light on
• Transmission shift concerns, slipping and damaged clutch(es) or band(s)
• Engine driveability concerns, poor acceleration from a stop, limited engine RPM range

The oil that is used on these air filter elements may be transferred onto the Mass Air Flow (MAF) sensor causing contamination of the sensor. As a result, the Grams per Second (GPS) signal from the MAF may be low and any or all of the concerns listed above may occur.

When servicing a vehicle with any of these concerns, be sure to check for the presence of an aftermarket reusable, excessively/over- oiled air filter. The MAF, GPS reading should be compared to a like vehicle with an OEM air box and filter under the same driving conditions to verify the concern.

The use of an aftermarket reusable air filter DOES NOT void the vehicle's warranty.

If an aftermarket reusable air filter is used, technicians should inspect the MAF sensor element and the air induction hose for contamination of oil prior to making warranty repairs.

Transmission or engine driveability concerns (related to the MAF sensor being contaminated with oil) that are the result of the use of an aftermarket reusable, excessively/over-oiled air filter are not considered to be warrantable repair items.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

This bulletin was specifically for the K&N brand CAI systems and was specifically for the V8 model Camaros across all Gen 5 production years.

I just wanted to give everyone a heads up on this as I found out about it today at the dealership. I'm guessing if you swap the stock setup back in before taking it in, you might be alright.

Anyway, thought i would share.

ummmmmmmm....

Lets ASK the GM Customer Guy who comes on here all the time

It would be your headache to fix it. Before buying the car you should have checked everything. If there were aftermarket parts then you should do your homework before buying it. GM is sell you a used car as is. They didn't install it so why would they pay for any repairs.

If it were due to the oiled filter you would think they would be blaming almost every intake instead of just one, although I know some K&N filters are a little heavy on the oil out of the box, and it seems most end users over oil them...

Just wondering what they are claiming specifically caused this?

I will look into it today and see if I can get additional information. I'm curious as well as to why it's specifically the K&N intakes.

I will post up an update if I can find any additional information on it.

My younger brother just bought an SS with a K&N on it from our dealer two days ago. That's what brought this all up because they had the car scheduled for GM Certification, but they could not certify it due to the airbox. So they ordered a factory airbox and in that process, the bulletin was discovered and they wanted to let me know about it so I could tell him if he ever needs service to swap the stock parts back in and he should be okay.

I don't actually work in service guys, I'm an I.T. technician..so let me get in touch with the people there who know more about this and see what I can find out.

I will say this information came straight from our service manager, so I would say it is on pretty good authority. He said they have had a few SS models come in that couldn't get warranty engine replacements because of the K&N bulletin.

That's all I know so far.

That makes sense, vehicles have to be all original to be certified. The resulting 'bulletin talk' was probably just that, shop talk.
Several of us on here have or do work in the auto industry, like yourself and know that 'shop talk' can spread f a s t

I'm claiming dealer !!! Some dealers will give people a rough time over mods; however, an intake...GEEZ. If this is the case, GM will eventually void warranties over all CAI's with oiled filters (highly unlikely). The Magnuson/Moss Act protects consumers who mod. The mod has to be undoubtedly responsible for the failure. If your stereo shorts out and you have a catback exhaust, the dealer is SH*T out of luck. I want this claim in writing.
