Good Day...I was doiing some routine maintanence on my 09 flhx and was cleaning my stock air filter which looks pretty beat. My question is this...I have done no mods to engine and was wondering if I upgrade only my air filter to a k&n and use stock cover if that would be o.k. for now until i get to the pipes and the fuel. I want to give it more air for now. Will this affect any other things in the meantime.Goiing on a 4,000 mi trip and wanted to deal with this prior. Thanks for your help.
