K&N filter- need to worry about the oil?

I got K&N filters for my M550i and I remember with my F10 M5 I had to be careful of oiled filters due to MAF sensors being ruined by oil. The filters I just opened have that pink oil on the edges and I wiped off all that I could see. Just seeing if anyone else has put these on their cars without issue?

Well, I let the filters sit with paper towels to soak any excess oil over night. Little bit of their pink oil was absorbed. The instal was about 3 minute per side so including opening garage and getting tool out to walking back in was only 10 minutes. A lot easier than I thought!

I let it set overnight before installing it to remove the excess oil.

No nothing noticeable, but when you have power levels like our cars it's tough to feel even a 10hp boost . I feel better about having them in compared to paper.

That's what I did with paper towels. They soaked some oil up

Per K&N website

We are aware of the "urban myth" created by a few dealerships that a vehicle's MAF sensor can be contaminated by K&N filter oil. No evidence has ever been provided to support this "myth" and years of diagnostic testing by K&N has shown that not only is this allegation not real, it is not even possible. In our opinion, it is an excuse for a dealership and/or the vehicle manufacturer to avoid a legitimate warranty repair. In the last 4 years, we have sold over 10,000,000 lifetime air filters and received only a few hundred calls from consumers who are having dealership or service provider challenges.

On my 2018 G30 540i the strut bar runs over the top of my air box. Does the bar need to be removed to take box off? I don't see how to do it otherwise.

I removed my air box and replaced it with a BMS intake without removing the strut bar. It is a tight area to work in but it can be done.
