Will TBI spacers work on SFI engines?

[spham]

Helix power tower, poweraid, ect... were designed for TBI engines right? what good can they do for SFI engines like mine?

A TBI unit looks and fits on an engine very much like a carburetor, it is centrally mounted on top of the intake manifold. the spacer is placed between the TBI unit and the intake manifold to simulate a hi-rise type intake, for the power increase. The SFI and multi-port engines are designed totally different, the spacer will not fit, and the improved design of the intake makes it unnecessary.

Thanks, that certainly saved me some hassle
