I was wanting a better air filter but did not want to replace my stock air box with a aftermarket type air filter, so I have tried this as a replacement filter and so far it is working very well. The foam filter is from a lawnmower air filter that can be bought at most hardware stores that carry small engine parts. Take your air box off and use the old air filter as a guide to cut out the new air filter I also used the small mesh that came with the filter,after testing it for a good fit go ahead and oil it up reinstall the air box with the new filter and your ready to go. this filter is denser than the stock air filter and catches a lot more dust so be sure to check it regularly.
