Summit is selling a unit called a Helix power tower.
This 1" spacer bolts between the throttle body and intake manifold. It is cut with grooves on the inside to swirl the air.

cost 89.99 for87-93
claims 20 horse increase

this doesnt seem to restrict flow like a tornado unit.


does anyone out there know if this is legit, or a rip off?

Thanks
