I installed my BHAF and wanted to know as I took out my k&n is the BHAF better than the k&n when it comes to flow rates etc. My search will not work on this site with 4 letter searches for some reason. ALso I took a plastic wire tie and ran it through the metal in the filter and tied it around the AC line next to the fender just to secure the fliter from moving around. Not too tight just snug. Are you guys securing the filter or just leaving it lay there??? THANKS
