I have started looking at air cleaner and filters. I would like your input and wisdom on the matter. In the VB catalog I have been looking at the K&N part #3-1802, filter #3-1811, or the flat chrome #9-103. I would like to know real world and first hand from you guys. Are they worth the money or what do you recommend. I have stock as of now, which seem to be alittle restrictive to me. I plan on a set of headers, new exhaust and a harley muffler upgrade. I will say I am a sucker for chrome. I come from a Harley and hotrod back ground. So please, any input would be great, thanks.
