New Air Filter

[dberger]

I need a new filter for a 1998 528i. Bav Auto has a Million Mile Filter by K&N for around 40.00. Is this the kind to get and what is needed to clean it?

I hear K&N air filters don't do crap to your car, save a different noise at higher RPMs.

The filter for the 5-series is pretty swanky.

dberger,
I have one of those installed in my car. It's hard to tell the difference if there is any improvements in horsepower or fuel ecomy. I only get about 13mpg around town, must be the way I drive. Anyway, as for any noises at higher RPM'S it's news to me.

I have heard some negative stories though. It seems like overtime the MAF valve could fail (plugged due to excess oily dirt). But then again, you only have to clean the valve to fix the problem. I have not expererience any of this for your information. Go to product reviews for additional information on this forum.

Thanks for the info.

The noise at higher revs relates to the K&N induction kits - cone filters. What you are looking at is just a straight swap for your original filter, these supposedly offer better airflow with the same amount of filtering.

However, they are supposed to last the lifetime of a car and are henceforth a little more expensive. The downside is they need to be cleaned using an oil every couple of years or so, this can lead to oil getting on the MAF which doesn't do them a lot of good. I think K&N say you get a 1-3bhp gain from using these filters but I wouldn't hold my breath.

At the end of the day this could be the last filter you ever buy for the car, and if you clean/oil it properly should give you no problems at all - the choice is yours.

i concur, this is the only filter you will ever have to buy, its a great investment. i didnt notice a huge difference in power in my car, but i guess the acceleration was a little bit more responsive, i dunno but i could kind of feel a difference (note: i also have my engine debaffled)
