They're better than a k&n. If you run a k&n for awhile and then look at your turbo wheel, you'll see where its starting to get dusted. The 6637 is alot better, and its cheaperIm going to pick one up sometime this weekend, are these filters just as good as K&N and......... I want something that is going to give me more power and at the same time filtering more dirt.
WOW,, um I don't think the Donaldson is better than the 6637... you don't need the mounting band either, the filter will lay right on the fender well just fine,And the Donaldson in The Tymar kit is better than the 6637 and usually much cheaper. You will need a mounting band for the filter if you want the added air flow the filter provides...The Tymar kit comes complete and has a new battery tray.
They are better than the K&N drop in panel filter... The panel filters don't seal very well allowing dirt to pass through.They're better than a k&n. If you run a k&n for awhile and then look at your turbo wheel, you'll see where its starting to get dusted. The 6637 is alot better, and its cheaper
Not bashing them at all. The drop ins don't seal well, it is a verifiable fact. The cone type, I have the same issue as I do with any filter that I have to do maintainance on.I all ready have a big K&N filter people on here just seem to bash them, and I dont want to hurt my motor.
