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 ????
Pros: fun to replace filters
Vehicle:
Ford Bronco
Mileage: 35405 km
I purchased K&N drop-in engine & cabin air filters. They are ridiculously easy to access and change yourself- and you’ll never have to buy air filters for as long as you own it.
Pros: easy to access, never buy filters
Vehicle:
Hyundai Santa Fe
Mileage: 105000 km
Drop in K&N worked good for me.
Pros: worked good
They're good filters, very good, but they're not worth the trouble for most people. It's rare that anyone really keeps up with the instructions for those filters to a TEE, and not following those instructions can have repercussions. My dad used to use them, and would have me use them as well when I was younger, but they were not worth the trouble, and fouled up sensors because be didn't do X, Y, or Z properly. And when I read the directions myself, I realized he never did the maintenance properly (such as the oiling, drying). I threw mine out and his as well. If you're going to follow all directions to a perfect tee, they're really good. But that +2HP or whatever is not worth it for me.
Pros: good filters, potential for +2HP
Cons: not worth trouble, fouls sensors, complex maintenance
Return the k&n filter and stick with the stock motorcraft.
A K&N filter will significantly reduce engine life. It lets in more particles than the OEM filter.
Cons: reduces engine life, lets in particles
Swiss cheese air filters (MWR, K&N) will do a number on your valve seats. Ask me how I know If you buy it, swap back to OEM or get a Spint DNA filter. I have a whole superbike engine build and the hp trade off isn\u2019t worth it.
Cons: damage valve seats
Mileage: 3000 km
K&n filters for low mileage things like a motorcycle, cool. For a commuter car, pain in the ass. I would much rather quickly swap a filter for a few dollars vs cleaning, drying and re-oiling every few k km.
Cons: pain in the ass
