Nitrous Oxide 0.500 Yellow Billet Square Bore Perimeter Injection Spacer Plate

These Speedmaster perimeter plates employ multiple injection points to ensure that a perfectly atomized, cylinder-to-cylinder balanced blend of fuel and nitrous reaches your engine. The technology eliminates nitrous delivery imbalance, the major drawback with spray-bar type nitrous systems. The plates are manufactured from aluminum and are anodized for protection.
