Best of all, the ARP indexer is made from aluminum alloy with precision machined threads that allows you to proof the quality of spark plug threads before installation in expensive cylinder heads. Anodized for protection and quick recognition. For use with tapered gasket 14mm plugs. Spark Plug Indexer Size 14mm
