K&N universal air filters feature a special design that allows for direct attachment to the carburetor's neck, replacing the stock air box and filter element. There are four available styles: round straight, round conical, oval straight, and oval conical.

Features:

• Attach directly to the carburetor's neck.
• Parts with RC prefix have chrome end caps.
• The rest are made of black rubber.
• Pleated design that increases air flow surface area.

For proper fitment, it is important to match the external diameter (OD) of your carburetor's neck with the internal diameter (ID) of the filter, as indicated in inches and millimeters.
