I don't know about you but I will stick with my AC DELCO filters.

 

Filter Review / Test

[Silver2K4Z71]

Good find! I have a K&N on mine but am thinking about switching to something else.

The good news is that Advance/Discount Auto parts sells A/C oil filters for $ 4.50. Not a bad price for the OEM filter. A lot better than what GM dealers charge.

Do not know the price of an air filter, but Advance sells those too.

Never use a K&N in a vehicle that has a MAF sensor. The oil will accumulate on the sensor and cause all kinds of problems.

Just about every modern vehicle has a MAF sensor. K&N would go out of business if nobody used these filters on newer cars. I personally do not use them, but a lot of people do.

pretty much common sense. the K&N lets a little more dirt through because it flows better. but, K&N's capture more dirt once a bit soiled, so that could affect the test. they best filter out thee is the MAHLE or MANN(

German), they have been tested to catch more dirt AND flow better than respective K&N filter panels on BMW's. they are just regular paper filters.

DO THIS

DON'T DO THIS

 

First, Inspect the vehicle for a reusable aftermarket excessivelyover- 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.

that's why I installed an aem drylock filter-no worries and supposedly filters better than oiled

the oiled air filters are supposed to go 50k before reoiling? anyway right? and of course more is always better when washing and reoiling LOL

[swilliams1005]

Yeah had a K&N Filter and ruined my MAF and has caused a bunch of problems for me.
