"I bought the power tower because your add said I would get better gas mileage. And I did, picked up 21/2 MPH with out changing my driving habits. The torque and responce was a gift. I drive a full size chevy PU and recomend the helix tower. Very simple to install, just needed one hose to be longer. Simple change. Steve from Raleigh." —Steven M from Raleigh, NC bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2004 Chevy Silverado, 5.3L V8.
"Super easy to install, it only took me about 10 minutes. There is a very distinctive whistle, I believe my K&N 77 series makes it even louder. I did not notice a big difference in the power, but my fuel efficiency has improved by ~0.5-1 MPG. If you are like me and you want to save a few bucks at the pump, this is a good start." —Steven T from Havelock, NC bought an Airaid PowerAid Throttle Body Spacer for a 2004 Chevy Silverado.

Performance & gas mileage are excellent for the price." —Dale C from Anderson, IN bought an Airaid PowerAid Throttle Body Spacer for a 2004 Chevy Silverado, 4.3L V6.
"by itself it's pretty good. But with a exhust and new k@n air filter it's great. But on my 5.3 04 silverado I had to cut the fan crowel to make it fit" —Jon A from Des Moines, IA bought an Airaid PowerAid Throttle Body Spacer for a 2004 Chevy Silverado, 1500, 5.3L V8.
"this spacer worked fine on my truck, it saves ALOT OF GAS..!!! and conserning the power it gives it does make a difference." —Hector D from Pasadena, TX bought an Airaid PowerAid Throttle Body Spacer for a 2004 Chevy Silverado, 4.3L V6.
"I ordered the Helix Power Tower along with a Spectre Speed Cold Air Intake. Both arrived in the estimated time (5 days) with free shipping! I installed both items in approximately 30 minuets without any problems. The instructions for both provided pictures which made installation easy. I have some experience working on cars however. The throttle body does put the intake on the fan shroud and very close to the electric fan. I trimmed a very small section of the shroud to prevent rubbing the intake. The hardware supplied with both worked well and appears to be good qualitly. I noticed an immediate gain in horsepower through the lower gears when I put my foot in it. I am still on the first tank of gas and can not comment on the final mpg gain. I have used about half of the tank and I have gone 160 miles in mostly city driving, trying my hardest to stay off the skinny pedal. I do hear the whistle that other reviews talk about but its not too loud and I had to turn the radio off and listen for it. I would recommend both products to anyone!" —Mike S from Apple Valley, CA bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2004 Chevy Silverado.
"The Taylor cable Helix is deffenitly one of a kind product. Installation was as easy as tiing your shoe,and took me only 20 minutes to install in my 2004 silverado. It looks cool and I even get that sweet whistling sound when I hit the gas! There's more power when I need it, and I'm getting more gas mileage too! I would recommend this product to any one who wants more horse power and more gas mileage for a great price! I couldn't ask for a better experience then the one I had with autoanything.com. Thank you so much and looking forward to all the other great products you have!" —Scott J from Monson, MA bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2004 Chevy Silverado, 5.3L V8.
"Installation was very easy taking only a short time. I primarily use this vehicle for towing my travel trailer and will be taking a trip this coming weekend. Pulling it over one of the mountain passes here in Washington State should give me an indication of whether or not it has been a worthy investment. As far as the truck goes ('04 2500HD w/ 6.0L) I have added an OEM replacement K&N air filter, a Flowmaster 70 series muffler and a Diablo Programer. The only other upgrade I am considering is a cold air intake system." —Scott B from Spanaway, WA bought an Airaid PowerAid Throttle Body Spacer for a 2004 Chevy Silverado, 2500HD, 6.0L V8.
"I have a 04 silverado 5.3, was my dads truck, the best he says he ever got was 17.4 avg. on highway after install I got a strong 20 mpg, and the performance is AWESOME, slight whistle at all rpms but not unbearable. A few modifacations were needed but install was easy. Would recomend product!" —Michael S from Standish, MI bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2004 Chevy Silverado, 5.3L V8.
