Personally I like K&N filters, they come with a nut welded to them so you can use a normal wrench instead of a filter wrench. Gotta be careful not to over tighten them though
I have a kn 1 on my truck and winter is about every 1k miles I empty it. Its the 6oz canister and usually about half full. From may till like October I dont even have to look in it because it doesnt get more than an oz of oil build up in it. But man winter time with the condensation sucks.
Not sure about mobil1 filters, but stay away from K&N oil filters. I've just used one for an oil flush after extensive maintenance work, and after just 100 km it had collapsed.
K&N filters are some of the worst quality filters on the market.
That won’t happen if you were using a K&N oil filter. All these cheap brand filters are not sturdy and will collapse when you’re trying to take them off when stuck… either The Black K&N select filter or the white Premium filter will avoid this problem from happening…
KN filters are gay, watch freedom worx YouTube video about Oem vs KN filters. You'll wanna swap right back!
Also the K&N oil filter is superior to HD’s despite the recent upgrade. The K&N has a better flow.
K&N HP1002 because it has a hex on the end that makes taking it off through the wheel well really easy. Don't even have to jack up the car, just remove the rear splash guard.
That is why I always buy a k&n filter where can just use a wrench.
I put a K&N nut topped filter on it and never had to do that again!
