I'm completely happy with my 2009 FLHP. If there is one thing I notice it's that it just feels like it's wanting more air. I'm not interested in changing my stock pipes or anything, but doesn't Harley make/sell an upgraded air filter that you can simply pop in to replace the stock, without adjusting anything, just plug and play and improve performance/gas milage? I don't think I'm interested in the K&N filters. Thanks in advance.
