Questions & Answers
This filter requires oil every time it's cleaned? or is there an oil less version?
By SOL
Yes, filter oil is always recommended whenever you wash your air filters. You can certainly run this without oil, but your engine will be less protected from road debris since oil plays a large role in trapping uncharged particles as they pass through the cotton gauze filter element. There is no oil-less version of these filters.
can i get in chrome?
By Duck
Once you select your exact machine from our fit guide, you'll be presented with all of the color options for this air filter kit. We do indeed have them in chrome for most models.
