I have purchased a K & N and when I get back this week I'm going to install it. I've never had a problem with K & N's and have had them in over 10 different types of cars over the years.

I had a K & N filter in my 911 cab and B & B tri flow exhaust a few years ago when I had that car and never had a problem with that MAF on that car, I have K & N on almost every one of my limos which some of them can get 75K miles in one year, and none of these cars have MAF problems or any other problems related to the K & N.

1. Why would the boxster be so hurt by K & N's and none of these other cars including my 911?

2. Also I'm thinking that alot of the problems occur when people are cleaning their K & N and over oil it too much?

3. What is your take on how much oil comes in the K & N filter when its brand new out of the box? I don't think they overoil it at the begining , maybe wipe a little off ?

4. Do these MAF go bad on their own? Is it possible they need to be cleaned / replaced every few years even without a K & N? Has anybody had MAF problems without a K& N?
