Good afternoon fellow COG's. I am about to send in my ECU for the Guhl reflash and am sourcing a Vance & Hines CSOne. My question is....is there a need/benefit (outside of the serviceability) to replacing the factory air filter or does the factory filter flow pretty well? If there is a benefit....which of the aftermarket filters is preferred?
My understanding is that the stock air filter may actually give better all-around performance than the K&N type. I have no direct experience to draw from here, just "hearsay". Basically, better filtration + same power with stock. That's the kool-aid I'm drinkin'.
Thanks Professor! Appreciate the response, the info and the supporting link. Very helpful.
