    I have an '09 Silverado with a 5.3 liter and would like to know besides a K&N what would be best to increase the fuel mileage a little bit? Thx!!

    Welcome to the site! From what I'v seen on this site, "freeing up" the exhaust (Flow Master; Magnaflow; etc) is good for the next step, then maybe a "Programer" or "custom tunr" for the computer. Good luck and Happy New Year!
