For my 2006 Hummer H3, this was the easiest thing to put it. You leave the bottom half of your stock intake air box in place and literally drop this into it and use the factory snaps to hold the new heat shield assembly in. I've driven about 250 miles since I put this in and my gas mileage has improved about 2-3 mpg. Which for me, is a lot. I've gone from averaging about 11 mpg to between 13-15 mpg. You can definitely tell a difference when you really step on the throttle.

I put the Airaid PowerAid Throttle Body Spacer on my 2006 H3 Hummer with the 5L engin. At the same time I put on the K&N Cold air intake. They both work great together. I have had it on for 2 weeks and get about 3 to 4 more mpg on the Highway. Also notice an increase in pickup when moving into passing gear. The Throttle Body Spacer makes a small whisteling sound , but not to loud. You cant hear it at all with the radio on. Some people like the sound it makes, but it really is not that noticable.

This kit was very easy and straight forward to install. The system components are very high quality and the fit was perfect. I went with this kit because I wanted to keep a relatively stock appearance and didn't want the increase in noise that is commonly experienced with more exposed kits. I feel that the price to performance/mpg ratio for the Air Raid kit is unbeatable. It definitely opens up the the intake system and allows it to breathe much more effortlessly than the stock set up.
