The BMC single oval conical air filter with a metal top is a universal element sized for a 50mm inlet and 66mm filter length. The oval footprint suits installations where a circular profile won't fit, and the 50mm connection adapts to common intake tubing; it provides a compact conical filtration option for retrofit and custom intake assemblies requiring an oval shape.
