Helix Power Tower
Is anyone running a Helix Power Tower throttle body spacer (or another brand)? If so, what do you think of it? Did it produce any significant performance gains? What about mileage? Thanks in advance for any input.

hey, i have one on my 1990 f-150 with a 351 and i had one on my 1991 with a 302. Everey in crese in power and fuel mileage you get is mental. These things do nothing but make a little noise when you have the pedal at a certain point. People who think it made a differance believe it does because its the only way to justify to themselves what they paid for it

Thanks for the replies. I've been looking at this thing & I can't see how an extra inch can improve velocity, especially since the throttle body feeds horizontially (no gravitational factor). I didn't know what effect the "airflow vortex" might have. Thanks again for the input & for confirming my thoughts.
