"Easy install other than a little tight around the cooling system hose clamp under the throttle body. Stretches the electric wires that plug to the throttle body a bit too. Nothing really you can do about that. I just cut the wire wrap guard back a tiny bit to take the strain off of the wires. I was worried about that. Delivers promised low to mid power gains. Whistle noise not a problem with me. Sounds great and only really heard on hard acceleration. Engine temp runs a bit higher than before.. Temp needle quickly goes to about the half way mark and stays there. According to techs, that is normal and not a problem. I'm satisfied with my purchase." —Dennis S from Oswego, IL bought an Airaid PowerAid Throttle Body Spacer for a 2005 Ford Mustang.
"This spacer should come stock on the car - why didn't Ford build it into the engine?!? The Jet Power-Flow TBI Spacer corrects a serious design flaw in the 3-valve 4.6L modular intake.
While there are many theories as to HOW it works, few debate that it actually does work for the new Mustang GT.
The most convincing theory I've heard is that the stock throttle body has butterfly valves which tend to vibrate -luckily this spacer creates pressure to stabilize them and makes for a much more responsive throttle.
A very noticeable mod to a stock 05/06 Mustang GT. I don't doubt that it also may have improved the car's response to its later SCT tune." —Richard B. O from Lauderhill, FL bought a Jet Power-Flow TBI Spacer for a 2005 Ford Mustang.
"I noticed a considerable increase in power after I installed the Helix spacer in my 4.0 Ford. As a bonus, it gave approximately 2 additional MPG. It'll pay for itself in gas savings. Nice product!" —William E. J from Oak Park, IL bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2005 Ford Mustang, 4.0L V6.
"I guess this might be worth about 1 rwhp. There is a slight whistle sound but unless you are trying to listen for it, you probably won't hear it over Magnapacks. I can't tell a difference by feel...I would have to dyno before/after. I think JET should provide instructions with it...although I figured it out eventually. It is a very tight fit with my C&L CAI on already." —Keith L from Mason, OH bought a Jet Power-Flow TBI Spacer for a 2005 Ford Mustang.
"I installed this on my 2005 Mustang GT, only to hope it will mix the nitrous and fuel mixture alot better when it enters the intake manifold. Easy to install, makes a whistle noise, but doesn't bother me. not sure if it added any horsepower or mpg, but it's mostly for what i first mentioned." —Travis P from Sumter, SC bought an Airaid PowerAid Throttle Body Spacer for a 2005 Ford Mustang.
"2010 Challenger 5.7L R/T with Corsa Sport Cat-Back exhaust, K&N Cold Air Kit & Hypertech Power/premium tune - smooths low end, obvious low-end torque drive-ability. No appreciable change in mileage either way - 19 or so mixed driving, 22-23.5 all highway. Excellent. Seems a lot for a few ounces of aluminum but remember the engineering costs. Maybe not the fastest car on the street but WAY more competitive with the additive improvements. Ordered a second one for my other 2010 R/T MOPAR-10." —Bill W from Bulverde, TX bought an Airaid PowerAid Throttle Body Spacer for a 2005 Ford Mustang, 5.7L Hemi.
"Easy installation, and I seem to notice improvement is throttle response and improved gas mileage from 17-19 to 20-23. I recommend this." —Kent S from Victorville, CA bought a Jet Power-Flow TBI Spacer for a 2005 Ford Mustang.
"i didnt know that it wont fit my BBK twin 62MM throttle body.. then i realized that it will only fit the stock throttle body which made me RESELL it for another mustang owner
to be fair.. it looked good but it didnt come in different diameters" —Abdullah K from Springfield Gardens, NY bought a Taylor Cable Helix Power Tower Throttle Body Spacer for a 2005 Ford Mustang.
