I own a 06..1500 5.3L i bought a Volant cold air intake with the optional ram-air tube and found a conciderable difference in throttle responce...aprox 1.5mpg improvement on city (havent checked on the freeway) well worth the money in my opinion.... took me about 30 min to install the whole thing and am very happy i bought it....
