"I JUST RECEIVED MY AIRAIR SPACER .SO I THOUGHT THAT I WOULD INSTALL IT RIGHT AWAY .IT WAS SO SIMPLE IT ONLY TOOK ABOUT 30 MIN.I NOTICED THE TORQUE DIFFERENCE RIGHT AWAY .THANK YOU FOR THE EASY ORDER FROM AUTOANYTHING. SIGNED. BILLY BRUNSON" —George B from Winter Haven, FL bought an Airaid PowerAid Throttle Body Spacer for a 2004 Ford F-150.
"I rated the throttle body quality low just due to the fact that the 4 bolts included with the kit are the same length as the ones that are removed. The installation would have been less than 30 minutes had I not had to go purchase 4 longer bolts. What a pain since I had my transportation torn apart. I haven't run through a tank of gas yet, but I think I'm getting better mileage. Time will tell. There seems to be a nice improvement in low end performance and the noise is not very noticeable. At this point I'm glad I purchased it and will install on my wife's vehicle when I verify the mileage improvement." —Tom R from Bellevue, OH bought an Airaid PowerAid Throttle Body Spacer for a 2004 Ford F-150.

My truck has leveling kit and 33x12.5x18, before this got 12-13 now 15 mixed driving. Overall, great investment." —Jr F from Granite Falls, WA bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2004 Ford F-150.
"Just installed the Jet Flow spacer along with a K N Air System and it is a bit soon to evaluate these parts with the exception that my F-150 has greater accelleration.It seems to run more effortlessly as well. I am opptomistic that performance and gas milage will be increased as well." —Andrew B from Manchester Center, VT bought a Jet Power-Flow TBI Spacer for a 2004 Ford F-150, New body style, 5.4L V8, 8th digit of VIN = L.
"Installed in minutes and looks great! Only problem i have with it is it whistles quite a bit if you run cruise at 50-70... otherwise the whistle sounds great! Because you just hear it a little when you get on it or let off. Maybe a little power increase, and hav'nt drove with it enough to see about fuel economy, but then again my truck gets about 14 to start with so probly wont notice much." —Lee K from Bradley, AR bought an aFe Silver Bullet Throttle Body Spacers for a 2004 Ford F-150, New body style, 5.4L V8.
"the only thing this throttle body spacer really does is make a stupidly loud whisttle.
although i did get somewhere around a 2 mpg gain" —Adrian M from Victorville, CA bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2004 Ford F-150, New body style, 4.6L V8.
