The Cyclone Ultra Filter design uses centrifugal force to keep dust and dirt out of the filter element which increase filter life. Advantages: 8”rnd. x 12in.Lg Filter Element x 15-3/4 O.A.L. w/ 4" Inlet Cap. Don’t mess with the rest, buy the best!!! The Cyclone Ultra Filter design uses centrifugal force to keep dust and dirt out of the filter element which increase filter life. Advantages: 80% increased air flow as compared to single inlet filter systems. Velocity fins direct 99.9% of the dust out of the filter. Filter element is easily removed from either end. No oil required on the filter element, which can cause damage to engine sensors. Filter end caps are machined from a single piece of high strength 6061-T6 billet aluminum. Not spun aluminum! Available in 15” length (p/n CF-815-4). Custom mounting clamps (not shown) allows fast easy filter removal. No external welds to crack or leak. Super strong, tough and durable. All filter components are Chem.-filmed to remove all foreign debris, which ensures nothing but clean air gets into your engine. Chem-film also allows for easy cleaning. Patent Pending
