so i was looking on the internet the other day looking for cheap and easey bolt on preformance accessories for mt 96 f150 5 spd (300ci) and came across throttle body spacers. I cant quite remember the actual price but i remember they were'nt too expensive. So my question is how much power do they actually add and is it even noticable?

 

Check with the guys in the 4.9L forum.

 

They look good, but that's about it.
