K&N - KT-4511XD - Top Filter

K&N Air Filters were originally pleated to increase surface area and capacity for harsh desert conditions. 40 years later, this same filter design continues to provide low restriction while offering both high performance and capacity. Updated with XD Components, K&N’s patented XStream® Series Motocross Air Filters feature revised seals, increased pleat depth, and a tri-star injection molded top for increased strength, capacity and performance.
