i have a 2013 silverado 5.3 with a hypertech programmer and a 40 series flowmaster... was wondering if i should get a cold air intake as well. have heard mixed reviews on the Chevy stock intake. some saying that the intake is great from the factory and it would be a waste of money to buy a new cold air kit for it. others saying that a cold air is the better way to go.

what do yall think?
what it the best route to go?
