K&N Air Filters

for the Yamaha Rhino 660 04 - 05 and 450 06 # YA6504 K&N Air Filters increase performance and horsepower. K&N is the innovator of a unique cotton air filtration system. As a rule, no jet changes are required with just a K&N filter element, but the spark plug condition should be checked for proper mixture after the first few miles of riding. If the air box has been modified for increased air flow, the main jet size will need to be increased to provide the proper fuel mixture.
