This was easy to install, and most importantly gave great throttle response and power you can feel. Definitely worth the money.

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.
