Black anodized with a Contrast Cut machined finish. The design for the Vintage air cleaner is taken from the Performance Machine Vintage caliper design and in doing so a style matching Vintage Family was created. Like with the Vintage calipers the styling looks retro; but not so for performance; which is on the highest level. The induction opening clearly reminisces to ram-air intakes; allowing air to travel charged and virtually unrestricted through the high performance K&N filter element. The PM internal crankcase breathing system ensures a clean; low profile and lightweight package. Bolt-on install with the included installation hardware. - CNC machined billet aluminum - Incl. pre-oiled K&N high performance air filter element - Internal crankcase breathers - Bolt-on installation - Includes installation hardware - Incl. spacer for 114" models Note: Style matches with PM´s Vintage calipers.
