I have not personally used one.

But from the looks of it & design,I would have to say it will increase fuel mileage,even w/a mild cam upgrade from stock,should do nicely.

The intake port velosity should increase,therefore giving you more low end torgue.

I have witnesed (SP) & drove first hand,a SP2P intake on a mild SBC 350,,,let me tell you,it had all kinds of bottom end torque,but it also had no top end power,not even close to the top end a SBC Perfomer intake.

On the SBC SP2P intake the RPM range is very low.


Here is one now for sale.
