Drop in filter?
So guys been doing a little reading and it seems like the drop in filter is the place to start. So which one is the best? Thanks in advance.

Don't want to go too OT, but when did the larger filter start being used?
My filter for my 2008 doesn't fit my 2011 car. OP, the main difference is some are cotton filters (you can wash them), and some are are paper filters without the charcoal layer. Supposedly, the charcoal free ones are used in Europe. .

Why stay away from the dry?

The 2008-2009 filters have a charcoal filter which is really restrictive. That's why swapping these older filters is much more beneficial. - KJ |

I was told that the oil does about 90% of the "trapping" and that dry is more of a race thing when you need absolutely every last bit of power you can get. Not worth it in my opinion

K&N has been making oiled filters longer than anyone else. They know how to do it. And they are priced reasonably for the E9x M3 application.

yes oil does help w/ trapping. But oiled filters flow a little better, using the oil also to help filter. A dry filer does not flow the same, so in essence a oiled filter flows more cfm hence why I (at least) prefer oiled filters. there is no maf sensor to foul on these cars and IMO the people that do and then bad mouth the filter, don't know what they're doing

Weird, because my filter for my 2008 M3 is about 1 inch too short for the 2011 car.

On their cars with no issues, dry works quite well and is safe haha. I thought from a common since stand point that the oil would trap better just because of how sticky that crap is lol |

Do a little searching and you will find that there are actual numbers on filtration. Whichever one you get makes little difference. I've seen nothing from an independent user who dynoed showing gains when it was done on a dyno that didn't belong to the people who sold it or the people who made it no matter what year. Unlike the older cars with the liner the newer ones don't get much of a savory sound improvement either. I could barely tell the difference between stock and the AA green filter.

the m3 (current gen) doesn't use a maf, it's a map sensor.. And do a little searching; don't believe all you read either. The problems people have with oiled filters fouling maf sensors don't know what they're doing. I have been using K&N oiled filters for 10 years in all my cars w/ no issues ever.

I was always worried I wasn't using enough oil back in the day lol. I would just give the filter a light "spritz" and it seemed to work find. Good to hear that I apparently don't need any oil
