I have been reading other treads where members have they installed them it would be nice to know if they work and how? I understand how they work on the strait up and down trottle bodies better draft is it the same for the sideways throttle body?

i installed one on my 01 4.6. i pulled it off for a larger throttle bodie. as for the spacer. i got about 1 exta mpg but no exta power. the tb gave what i think was a good power increase at about 2500 to redline.

Ford-fanatic73 save your money, I bought an airaid throttle bottle spacer, it lasted about a day, it just whistled, and no power increases. I didn't have it long enough to notice a gas milage increase. If you decide to still get one take lancekilgore's advice and turn up the radio.

I haven't tryed the spacers due to hearing they aren't worth the time. I do have a 75mm BBK tb. It helped my power & my mileage is better too. I can't say the tb did it. I added headers at the same time.
