Taylor Cable Helix Power Tower Throttle Body Spacer Reviews

2004 trailblazer 4.2 I6

Reviewed By caleb o (Sherwood, AR) Reviewed for a 2004 Chevy Trailblazer —5/31/2011 8:18 PM

It was very easy to install and took about 10 minutes. Made out of high grade aluminum. Got a good boost of hp but the gas mileage didn't change much. All n all good quality and I would recommend for other trailblazer owners.

Airaid PowerAid Throttle Body Spacer Reviews

Pretty cool stuff

Reviewed By Clyde L (Corpus Christi, TX) Reviewed for a 2004 Chevy Trailblazer —2/22/2007 9:17 AM

The installation was fairly easy with the right tools. I did feel a bit more power/torque immediately. No whistle at all!!! As far as gas tank does seem to streach a little further. I'm too busy stomping on the peddle though to be 100% sure. I have a chip, dual exhaust, and K&N air filter installed already and everything seems to work well together. Put it this way...I smoked a BMW X5 head to head on the freeway, so I like it!

Jet Power-Flow TBI Spacer Reviews

in additioin to the other upgrades installed

Reviewed By Robert S (HARRISBURG, PA) Reviewed for a 2006 Chevy Trailblazer —3/25/2017 8:23 AM

The Jet Power-flow spacer has helped the other engine upgrades that I have installed. These include a PCM of NC performance PCM, Jet Power MASS sensor and a Volant Cold air intake that connects directly to the throttle body. I'm not sure of the total HP/ torque increase, but this upgrades have made the 4.2L perform like a V-8 and has given a consistent 20MPG on the highway (highest was 23MPG on the highway) which is better than the 17MPG that I was getting in stock form.
