Installed this on my 04 gmc Sierra 6.0 and notice a great low end tourqe increase and gained 2-3mpg with every thing stock except my superchip tuner. Took me couple minutes to install and very well pleased with the overall purchase.

Taylor Cable Helix Power Tower Throttle Body Spacer Reviews

Helix Power Tower, a noticeable power difference.

Reviewed By CJ R (Spokane Valley, WA) Reviewed for a 2004 GMC Sierra —6/13/2011 1:07 PM

Well it was not as easy to install on my 04 GMC as it was on my 99 Ford F-250. Noteable gains in perform. and mileage. Wish it had the embedded gasket like the picture shows, would add in ease of installation and I tend to think a neoprenene gasket seals and lasts longer than a paper gasket. All in all it is worth the gains especially when other mods are added such as headers, mandrel bent exhaust,CAI, and A good tuner(I used superchips cortex) or tune. Has a noticeable whistle that I like.
