Not sure which 2003 Ford F-250 Throttle Body Spacers are right for you? We have over 1486 customer reviews, with an average rating of 4.5, to help you find exactly what you're looking for. Here's what some of our customers have said:
"The instructions were some of the worst I have ever seen. I had to go to the Jet website to find out which side faced in before I could even start the install.. And the throttle cable and transmission kick down cable "spacers" were as rudimentary as anyone could imagine. The long and the short of it is it still works as advertised. Great throttle response and noticeable increase in torque. No noticeable increase in MPG yet though, so the computer may still be adjusting. For all those other reviews that said easiest install ever etc, well they are either liars or 8 feet tall. There is no way this 6 footer can stand flat footed and do the install in 30 minutes. After the install info came back from Jet it still took over an hour and a half, cable spacers were the worst part." —James B from Warner Robins, GA bought a Jet Power-Flow TBI Spacer for a 2003 Ford F-250.
