I have a 2003 Silverado 1500 4.8L V8 and all that has been done so far is true dual exhaust with turn downs at the rear axle. I am considering an air intake and curious if it is worth and if so which one is the best to go with? Looking to start beefing the truck up but taking baby steps right now. Looking for any suggestions. Thanks

 

to tell you the truth your not going to feel much of a difference with a cai. your best bet is prob to get a hold of wheatley or blackbear and get a custom tune.
