Features: The Cobra system consists of a laser-cut, formed steel cover, separate mounting ring, and all the fasteners, seals, backing plate and mounting hardware for easy installation. Flows better than stock or competing units, in large part because of its unique internal venturi design of the inner filter. Slim profile keeps the unit away from the rider’s leg. Formed stainless steel mesh insert. Optimizes overall performance. Made in the USA. For '99 -'17 Twin Cam Delphi EFI and '99-'06 Twin Cam CV carb (except '08-'17 Touring/H-D Trike, '16-'17 FXDLS, '16-'17 Softails, '14-'15 FLSTNSE, '13-'14 FXSBSE and '11-'12 FLSTSE)..
