Airaid PowerAid Throttle Body Spacer Reviews


Works good

Reviewed By Scott J (NOKOMIS, FL) Reviewed for a 2006 Hummer H3 —1/7/2014 9:49 AM

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.

Worth the $$

Reviewed By Lisa C (Lyons, NY) Reviewed for a 2007 Hummer H3 —12/1/2010 8:06 AM

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.

Quest for Hummer power

Reviewed By George Y (Angleton, TX) Reviewed for a 2008 Hummer H2 —2/9/2010 10:59 PM

Received the spacer in a few short days. Well designed and fits to the intake perfectly. No whistling noise heard when running. Power increase wasn't pronounced but that would need a dyno test before-and-after installation for measurement. Spacer is used in combination with cold-air intake and cat-back exhaust. Together made major improvement in acceleration.
