Grandson says my 2012 Sierra 5.3L sounds BOSS!

Reviewed By GAYLORD H (NEW BERN, NC) Reviewed for a 2012 GMC Sierra —3/7/2018 2:06 PM

Took a while to remove the Mass Air Sensor from the OEM intake tube; mine had a plastic "keeper." Also, radiator hose mount of stock intake tube had to be pried up with a screwdriver. Otherwise, the install wasn't bad. Get a 5/8-inch drill bit from Tractor Supply for $10, or so, to drill the hole in the air box mounting plate. I'm getting more torque with this CAI and the sound IS BOSS when I get on it. Not quite like my 1971 Mach I Mustang's Big Daddy Thrush glass packs, but close.

It's a great product and defiantly gained horsepower! Next a chip and some tuning.
