Message: I just purchased a Street & Perfomance Electronics "Helix Power Tower" for my 2001 4.7L Dakota. I was looking for good or bad feedback as to wheather or not i affected their performance or fuel economy in any way? Also if there are any other mods that enhance the gains obtained from a throttle body spacer?
Message: Hey Nitro Junkie, I know the TB spacer don't work on 3.9, 5.2 or 5.9L engines because of the beer barrel intake. I heard there are some gains (or feels stronger) on a 4.7L v8 (different intake manifold).
Jermey - try it and if it works well then more power to ya. If not it doesn't work then its a rip off like Nitro said. Good luck.
