ProsMore pep, looks cool
ConsInstructions, no added MPG
Installed on a '09 Sierra 1500. 5.3 V8. Install was super easy. The only confusing part was the box, might want to include a bit better instructions on the air box, but other than that it only took like 45 mins to install. Gave the truck a better rumble and it is a bit more responsive on the throttle. I haven't noticed really any gains in fuel economy. Overall I'm satisfied with it.
