nice sound, easy install

It took about 45 minutes to install. After driving the trick for about a month I have noticed a slight increase in fuel mileage and throttle response. The biggest performance gain is when your accelerating under a heavy load.
Only thing I don't like is that it isn't a double cone filter. But it's also half the price of the top of the line systems.

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.
