All black finish. This is the Sidekick; your trustworthy companion in improving incoming air. The rear side of the forged billet and CNC machined filter housing is angled away from your knee; giving you additional leg room. Great example of functional design without losing esthetics. For the visual catch a translucent polycarbonate side window is used; with a special coating for long-term durability. The black synthetic high flow filter element is durable and wrapped in a stainless mesh. It is water resistant and requires no more than a rinse for cleaning. Oiling is not required. Note: A replacement clear polycarbonate side window is available as 936606. Note: The stock replacement air filter element is available as 708680. Note: These kits do not include oil reservoir.
