Boost your GM LS Series Engine's power with this Vararam Power Wedge. This wedge is not exactly a throttle body spacer, instead it changes the angle of the throttle body opening up the lower pathway to nearly 100% full volume, realigns the bore increasing flow velocity, and includes a balance plenum inside the bore, allowing the manifold vacuum to pull in a more uniform fashion. The gains from these features are up to 10% increase in airflow, up to 10% increase in peak manifold pressure, and power gains as high as 18 lb ft of torque and 14 hp on a stock LS-3 between 2500 and 4500 RPM. With the low price tag and installation time of 5-10 minutes, there is no easier way to add power to your GM LS Engine!
