Good luck trying that at any dealer except the one you bought it from. That would be my first choice, because they probably are mod friendly.

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 have been using an ADM race version on my car which has a Lingenfelter filter for 44,000. I don't know who the original mfgr is.

Per Andy's advice at ADM, I use the K&N cleaning and oiling kit with no problems at all. 44,000 miles and no engine codes or performance issues whatsoever.

Anyway, thought i would share.

Have you seen this bulletin or is there a strong possibility of dealer trickery? This just doesn't make sense.

Why cylinder #7 specifically? I'm not a motorhead but that doesn't make sense. Seems as if there was a problem then K&N would cover any issues with their product.

I work at a GM dealer,and have access to the bulletins,I can't find anything on that issue.
However there is an older one (from '07) out..

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.

#7 has always been the leanest on LSx engines.

[Higgs Boson]

exactly. cylinder 7 is always the first to go on the ls motors since 1997..... kn is probably the most commonly installed intake due to name recognition..... awesome of gm to blame kn, lol.

I am throwing the Bull $hit flag!! Provide a bulletin number.

[SSMickey]

So still no link to this bulletin? What about non-K&N intakes that use a K&N filter, such as the Halltech? Sounds like GM has found a way to blame there problem on the aftermarket if this is true. Wouldn't they have to prove the filter caused the problem and the #7 cylinder is a known problem.

[Neto1978]

Tks a lot, i was thinking about buying k&n, and thats why i will keep it stock!
