Decided to change my cabin filter today, I’m gonna be honest and forgot these had them. I think the P/O forgot to, the old one was dated May of 2003. Quick little before and after. Ofc bought the Mann filter, gotta keep it OEM ????
Has anyone bought k&n cabin air filter. Wonder how well they work
2023 Badlands and I love it…. Currently at 22k and just replaced the air and cabin filters with K&N it was fun ????
I bought a MANN filter for \\~$20 on Amazon and swapped it myself in under 30 minutes with a YouTube video.
Tbf, cabin filter always overpriced on BMW authorized dealer. At my local dealer, a standard carbon filter
(made by MANN) is thrice the price if you buy the same MANN filter without the BMW logo on it.
I got K&N cabin air filter and I'm so happy with it. This is reusable, washable and lasts easy for 80k miles
I've found K&N cabin filters are great as for the rest you need to run quality, especially your air filter since there are several bulletins about them and they changed the part because of P0299 popping up a lot.
Personally I already changed my stock battery to an AGM and will be installing a washable K&N Cabin Air filter when its next due.
I can tell you for sure the K&N flows better. the new stock filter definitely made me crank the knob up for more fan speed. the flip side is that the K&N does NOT do a good job actually filtering anything the size of sand or smaller. you will also be able to smell every molecule of exhaust and exterior air using the the K&N. stock filter helps reduce the scent of "outside"
I did the same mistake and bought these filters. They suck, just buy OEM or MANN filters (they are the same as OEM)
