The MAF is on the intake hose near the air filter box.

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?

I have a 1997 that has only had the paper air filters.

My air flow sensor was replaced a few yeas ago for a smog inspection. I can look at the invoice for the details.

I am sitting on the fence, which is contrary to my position 8 years ago.

But sometimes you can live and learn.

You may want to try the TRUEFLOW air filter. I did some research before buying my filter and to ME this one actually works better than the K&N filter. I have the completer cool-air kit with Trueflow filter in my Boxster and it works great. It's been in for over a year now and no problems. They NO LONGER make the complete kit, but do still sell the filter. It also comes pre-oiled. Again, no problems with my M.A.S. and looks like a better design to me.

what does the true flow usually cost?
