All black anodized finish. Compact in design with a 4-1/2" taper and a 22° forward angle for more leg clearance. Comes with a CNC machined base and radiused top cover. Complete with a washable high flow 4-layers pre-oiled black premium cotton filter element with all necessary gaskets; O-rings and installation hardware. Note: Breather design is O-ringed at the heads; passes through the backing plate and is placed inside the mouth of the throttle body. This eliminates external breather hoses so nothing will be taken away from the clean look. Note: See 988959 for optional rain sock
