Does anyone know how often I should replace my air filter. I installed a big sucker this spring and it is the open filter design with an outer chrome cover and the filter looks dirty. Also, can i put a k&n filter on the big sucker intake kit stage 1?

 

Big sucker should come with a KN filter. Was the filter red when you installed it???If it was just clean food and re oil

 

The Big Sucker filter isn't a K&N, but it can be cleaned and oiled the same way.
K&N part number 99-5000 is the recharge kit. You can get the recharge kit at most any auto parts store or bike shop.

 

Does the K&N 0800 Filter fit the A/N Big Sucker?
