Looks like that would have quite a velocity increase but then on everyday driver not sure it’s what one would really want either. Emulates the Boss 302 intake somewhat. Understand too that would be more for higher RPM and some low end torque sacrificed.
Jury’s still out with the TB spacers. Now those came on roadrunner engines from factory OEM thing. But undisclosed numbers as mine never had one. Nobody can explain this or if anything ever gained with them. Somebody may have answer someday?
Too tune required I saw, must increase air and Venturi effect making fuel ratios lean. Same difference with just CAI’s from the followings.
