I just picked up my V@H ovals yesterday.I'll be putting them on in the spring.I'm considering which route to go for air/fuel management. I'm thinking about a k@n filter that will give me high flow but still allow me to use the stock cover.As for fuel, I'm thinking of a V@H fuelpak.I like the fuelpak because I can install it myself. Any thoughts out there on this. P.S Did the air/fuel mod make a big difference for those of you that have done this? Thanks in advance for your comments.
