Arlen Ness Velocity 65 Degree Air Cleaner Kit For Harley
The Arlen Ness Velocity 65 Air Cleaner takes inspiration from the 90 degree Monster sucker, but makes significant improvements over performance. The unique, 65 degree angle gets the air filter way out there in the clean air, allowing it to suck up more air then imagined! Additionally, thanks to the forward facing design, banging your knee into your air cleaner is a thing of the past.
The Synthetic stainless jacketed filter features a synthetic material that is water resistant and never needs to be oiled. Just wash and re-use. The mesh supporting the gauze is made of a rust-resistant stainless steel as opposed to standard carbon steel, and the synthetic filtration gauze is in black or dark grey.The filters are hand-poured one at a time in a urethane body, unlike many other filters that are spun, which can leave a residue on the filtration media.
