You will also get a little bit of horsepower and torque due to the less restrictive intake. More air = better combustion. The added torque will give you better shifting out of your transmission. I would check the warranty before you make any decisions tho or at least get an ok from the dealer. I'm not sure on gm's take on installing aftermarket parts. It does only good for the engine but they are weird about things.
