I want to replace my single Filter for 6 K and N filters on my 97 Honda Valkyrie, what type do you suggest?
douglas f on Aug 12, 2019
BEST ANSWER: Douglas, thank you for the question. I would recommend for you to use a pod filter. In order to identify what size you will need, disassemble the stock air box and measure diameter of the inlet/connecting tube from the carburetor to the air box. After you have this measurement, try to get a rough measurement of how much clearance you have from where the filter will hit or touch the frame/any other component. It is to my understanding that it is a pretty snug fit so you might be sacrificing some air cleaning capability. A large air box and the square filter (OEM) would be something I would stick to versus the individual filters but if you really want to convert it those are the steps I would take to identify what filters you will need. Please let us know if there is anything else we can do for you by contacting us by email at [email protected], Live Chat or by phone toll-free at 1-888-339-3888. We are always more than happy to help.
