Hey whats up. Im new to the fourm, but ive been readin a lot and this is a geeat fourm. I am the new proud owner of a 99 986, ocean blue. Pretty much stock so far. My question, on sunday i installed a k&n air filter( before i read what they can do to my sensors) the next day i went to drive it, and the car was bucking and loosing power. Im thinking that the filter is oiled too much and i plan to take it out and go oem. Anyone have this problem, or have and ideas? thanks

COuld be too much oil, goto PepBoys and buy CRC Mass Airflow Sensor cleaner and clean any oil or dirt off your MAF, reinstal the stock filter and see if the problem comes back. If you really want the KN installed, wash the oil out of it and install it w/o oil but if you do this it will filter less.

Are you sure it was installed correctly? Make sure you did not put the new filter back in backwards. It has to be facing a certain way. I would also check your hose to the M.A.S. and make sure it did not come loose.

Ok ill do that. The MAF is at the bottom of the air box right?

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

Dude take the k&n filter out, even if you wash the oils out you will screw up your Maf, i had the filter for 5 months and had to replace my maf!!!! last week!!!

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?
