Great price, fast shipping. The install was very easy with noticeable gains in both power and fuel economy. Great product.

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.

Took less than 5 mins to install, very easy and no fuss! It doesn't make that high pitch whistle sound like the other spacers on the market which is good. I feel more power mid range but not sure about gas consumption yet as its only been installed for a week. Overall its a good buy and a nice upgrade for my H3's 3.7L I5 engine.
