Oil filter Mahle or K&N

I put a K&N nut topped filter on it and never had to do that again!

So far K&N is on track to hit 10k before I change my oil again.

In my time of ownership I've been doing oil changes are 7500 miles per the book with a full synthetic mobil 1 and a K&N oil filter since we got it with 155,000 on the clock.

For filters I use Mahle, if I remember correct that is also the OEM supplier, but costs half what a BMW branded one costs.

I’ve found them to be good

Filter Used : K&N HP-1008 (has a nut built into the filter for a 1" socket; recommended)

I personally don’t use k&n oil filters. They filter great but I’m not a fan of their flow.

Previously used the k&n one and it always leaked. After 3 filters, i switched

K&N is probably the most annoying with the rounded off nut they expect you to use to get the filter off. I'll never buy one of those again.

Cap was really stuck when taking it off initially. Also required Some force to get back on. When I first just installed new filter I got yellow oil light, still not great. Also noticed oil coming from gap between ofh and cap. And a drip from the top socket end. So end conclusion, mahle oil filters suck
