...for my 135i. Any feedback/suggestions/ideas on it? Can I find it cheaper anywhere else? What sold me on it is that it won't void my BMW warranty

^ Good call

K&N is crap. If you want a good, solid drop-in filter go to with Burger Motorsports

Here's the link:

What makes the BMS filter better then the K&N filter?

+1 K&N has been around for a while and i think they would put out a good product. I think any of the drop in filter options will be better over stock!

Derek8819 · 03-13-2012, 02:35 PM

+1 on K&N, they are the original.

Pleats (Specifically, deeper and more).

Urethane bleed. If you look at a K&N, some of the urethane "wicks" onto the gauze, which artificially lowers the amount of passable area.

BMS and MachtSchnell use S&B filters which are a higher quality.

I'm not saying the K&N is bad (Dinan uses it) but the S&B ones are just better.

all cotton filters do is let more dirt into your engine.... get a foam filter if you simply have to change, but I doubt there's be much performance gains. K&N is one of the biggest scams out there

Eddie135 · 03-13-2012, 10:35 PM

All filters are the same. Just cleaned and or changed more often, should be fine.

Have the k@n filter in my wifes 335i. Don't know if it gained any power, but at least it last a million miles.

+1

, I washed my K&N every 7500kms depends on the condtion.

SixBanger · 03-13-2012, 11:23 PM

ITG filter makes the best power out of all. Just call them wait a week or 2 and they'll make you the only foam filter available.

FIRST1 · 03-14-2012, 01:14 PM

Interesting discussion. Already purchased the K&N, Looking forward to seeing just how much (if at all) my performance, and MPGs will be affected.

K&N is a good brand, and I would trust them. But all filters are not created equally. BMW uses Mann filters from the factory, which they wouldn't do if Mann wasn't a quality filter brand, but clearly we upgrade the filters so they're not the best. K&N filters have layers of filter material with staggered thickness, while aFe uses progressive layers. Is one better than the other? I don't know. But I don't think the performance difference between a K&N, aFe, or S&B filter will be all that noticeable. However, there is a slight difference between oiled and dry filters.
