Product Reviews      Review part HA-4099

 I have two identical Honda 400EX quads, one of my quads has a K&N air filter the other had a stock Honda filter. Last fall we went on a 100 mile trail ride with two other couples on some very dry and extremely dusty dust trails. With six machines traveling together the dust in the air was thick. This spring as I readied my quads for the season I cleaned my air filters as directed and could not believe the amount of dirt that came out of the K&N filter compared to the stock filter which caused me to believe that much of the dust had past through the stock filter. I immediately ordered another K&N filter for my other quad. They are now truly identical quads.
