Been doing a little research and I kind of like the Volant and the S & B cold air intake systems. I am familiar with K & N since I have the FIPK in my 90 F150 4.9 for 8 years now and no complaints with K & N, but I kind of like the sealed cold air box that the Volant and the S & B provide.

My goal here is to improve MPG since it has plenty of power in its stock form. I also understand that the stock air filtration system does a pretty good job as is, so I am wondering if a CAI upgrade buys me much. Any suggestions recommendations would be appreciated.
