    K&N air filter with a Passat 1.8T?

    I recently read in another forum that you should not use a K&N with the 1.8T.

    Can someone confirm if this is true? I've been using a K&N in my 2000 for about 5 years. Is it a question of (over)oiling, or not recommended at all?

    If not good for the 1.8T, what alternative is there that offers the for increased performance of a K&N with a chipped car??

    The better question is, "What do you really gain?"

    I had mine in and I have a v6..but I heard that when you put one of those in the car, it could throw one of the sensors off since air filter is kinda oily. but I had no problems with it had it in for about 20000 miles so far. Most def beats the stock one.

    It is rumored that if the filter has too much oil on it, the extra oil could get released from it and put a coating on your MAF sensor. This would cause it to give false readings to your ECU, which in turn would cause your engine to run poorly.

    It makes sense to me, but I have been running a K&N for the last 15k miles with no problems. When you clean and re-oil the filter, it's a good idea to let it sit on a towel for about a day to let the access oil drip out.

    they key is to not over oil it.
    it comes fine in the box but alot of people over oil it then it messes up the MAF.
    there is really no difference between stock and k&n with gains.
    just preference.
