The Black K&N 57-1137 cold air intake kit fits 2001-2017 Harley Davidson motorcycles.

It can improve throttle response and uphill performance when towing, and it changes the engine sound.

The kit protects the engine from contaminants, installs with basic hand tools in less than an hour, and requires no filter cleaning for up to 100,000 miles. It has a 10-year/million-mile limited warranty. SKU: sku-770418261. UPC: 024844368508. Size fields: Length(In):, Width(In):, Height(In):.
