K&N E-4660 Air Filter Product Reviews

Tuesday, May 9, 2017 - Part E-4660
This element fits an aftermarket air filter that is no longer in production. I looked up the part number by dimension and it was in stock. Motorcycle is back on the road and customer is happy. K&N has been and will be my first choice in filters.
