2011 Silverado 4.8L
Probably the best current cold open air filter system out on the market right now. Install was not hard and took me about 45 minutes. If you get the add on open air snorkel like I got, which was the hardest part - maybe 20min for that alone. You can tell after the install that the truck completely breathes in much deeper and sounds deeper on exhaust also. Very happy with results!
Not too shabby
This short ram intake is pretty high quality, especially for the money. The rubber pieces and hose clamps they provide are top notch, the metal of the tube is better than expected as is the hardware. The instructions I received were vehicle specific, but were a little tough to get through due to the black and white photocopy quality. I have a decent amount of experience and common sense, so it wasn't all that had. Note that the kit comes with a K&N filter (which isn't stated anywhere).
