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.
NOTES 1. This is NOT a complete kit for removing the EGR system. 2. This product is to be used on offroad vehicles only. 3. This product does not meet emission standards and is not to be used on public roads.
