Air Control Valve (ACV) Block Off for Mazda 13B-REW Radium Engineering

This blocks-off the ACV (air control valve) port from the Mazda 13B-REW lower intake manifold. The low profile nature of the countersink stainless steel screws and anodized aluminum plate permits the necessary room for a secondary top feed fuel rail. Furthermore, deleting the ACV cleans up the engine bay by decreasing clutter and disarray.
