Description

Send your combustion chamber a performance-enhancing air charge without all the noise. Many throttle body spacers on the market are plagued by loud hissing and whistling. Thanks to the intrepid tuners at JET Performance, their innovative bore design eliminates unwanted sound, while still causing incoming airflow to smooth out and speed up. The result is an optimized mixture of air and fuel that gives you gains in the mid-range power band and even increases your fuel economy.

The JET Performance Power-Flow is designed for your specific vehicle and machined from aircraft-grade aluminum. The Power-Flow Throttle Body Spacer takes just minutes to install with no drilling or cutting.

Notes

  • The Power-Flow TBI Spacer is not guaranteed to fit with any performance air intake. Designed for use with the factory intake only.

"More throttle response. Smooth idle. Install was a little difficult due to incompatability with K&N FIPK intake tube. 15 minutes with a die grinder and a perfect fit with no fan clearance problems."

"Not often do after market parts fit as expected or perform to their design criteria. My 2002 5.4 F-150 received a healthy dose of go power with a Jet ECM module and TBI Spacer. The installation was reasonably easy, quick, and uneventful. The results were 2-3 mpg and much more consistent and powerful low/mid range. Good quality and easy power for the price."

"Amazing the way my F150 4.6l sounds and feels! I added an air intake at the same time as the TBI spacer and the sound is like a retro 4bbl kickin' in and opening up! The power increase at shift points is great! AAA+++"

"I am not that impressed with the spacer for my 5.4L F150. I think I might have noticed a little get-up at lower speeds but not for sure. It definitely did not increase my gas mileage and I drive the truck the same way as I did before the spacer. Not worth the money for me."

"my truck has 115,400 thousand miles on it and totally stock. so i installed a set of dual exhaust with glass packs and a k&n filter on it witch gave me good a good hp increase and also smoothed out my powerband. next i tried the JET power-flow spacer and installed it on my truck with no big problems. the power increase was well worth the money. it gave me notisable power from 1200-4600rpms. my gas mileage also increased 2 to 4 mpg!! good product and if i didn't have one alreadly i would get another one."

As good as advertised

"This product was as good as advertised, my HP and MPG changed immediately. (now to be fair I also have an AFE stage 1 cold air intake, so that probably is helping alot) It was quick and easy to install although the bolts that came with it were an 1/4" short but, that was nothing a quick romp to the hardware store couldn't fix. It does whistle faintly during hard accelarations but, its not overtly annoying. Over all its a great addition for a $100."

Worth the money!

Posted on 06/20/2007 by John B. - 2006 Dodge Magnum (Clarksville,TN)

"It took about fifteen minutes to install,knocked of 2/10's of my 1/8 mile time consistently. Don't really notice any MPG increase. There is a whistle to it when I accelerate slowly that can only really be heard with the windows down and it sounds pretty nice to me. Great buy for $89 I think. Looking at buying one for my Durango also."
