K&N AIR FILTER YAMAHA RHINO 660 04-05 YA-6504

Ideal for extended use in dirty and dusty off-road riding. K&N air filters provide clean carburation even at high altitude. No jet changes are required with a K&N filter element. Note: The spark plug condition should be checked for proper mixture after the first few kilometers of riding. If the airbox has been modified for increased air flow, the main jet size will need to be increased between 10-20% to provide the proper fuel mixture.
