My question is it true that these screw up your MAF ? I am in the market to buy one . Anyone give me the pros and cons

theres been lots of threads saying it does.i have one for about 5months and i have had no problem .

Stick to the OEM paper filter. K & N filter cost me $240 for a new MAF.

Well the Box is not the only car that has had a MAF destroyed by the filter oil, but it's still a great filter just make sure it doesn't have excess oil. Blow it off before installing.

How do you know its a "great" filter? Compared to what? What perceived benefits do you believe you have achieved by adding this filter to your car?

Just curious...

From my experience, I purchased a KN filter had it put in for about a day or two/ Then I started to search the post threads for KN filter. I didn't like what I was reading so the following day I took it off and replaced it with a original porsche part. Let me tell you I was able to sleep better at night. It's your call.....

More air flow, more dirt in the intake. If this is true, more dirt in the oil.

This dirt will actually show up in a used oil analysis. The recommendation when this happens? New oil filter.

To me, the K and N is an expensive gimmick.

To me!

After speaking to "mnboxster" and reading everal posts.. i have opted not to use the k&n filter i bought on ebay in fact I am trying to sell it to the second highest bidder with little lost out of my pocket . Thanks for the advice.

K&N was developed here in SOCAL back in the 70's primarily for offroad racing. They have now expanded into nearly every performance motor application. They are good guys. I have used their filters on racing motors since they first started out. They have been tested many times and found to let in both more air and more grit. If a $50,000 purse hangs on the winning car, K&N is my first choice. Will you ever feel the difference on the street or running Auto-X? Nope.

Porsche motors are expensive. I expect long life from my street car motor so I would not consider using a K&N on my Boxter. Every owner should decide for themselves with their eyes wide open.

I'll take your advice and just wait for a real intake for my car. I'm sure the difference is so minimal that it is negligible.

Me personally as a technican if anyone askes me questions like this i would respond.

A car company spends millions of dollar on research and development of this car OEM will be the best.


use oil air filters but don't over oil the filter, too much oil means your going to destroy your MAF. Its funny how many customer come in with Engine codes and destroyed MAF and car runs like crap because they over oil the filters ruin their MAF and the car is throwing codes.

Hey more $$$$ for the technicans =P

OEM is the best unless its a domestic car lol

Great discussion, but how do cold air intakes play in all of this. Don't they use gauze type filters with oil?

Thanks,
