This precision billet aluminium adaptor allows aftermarket water temperature senders to be installed directly into GM LS series cylinder heads. It thread-matches the factory metric M12x1.5 cylinder head port on one end while converting to a standard 1/8-inch NPT female thread for gauge senders. The compact design ensures accurate fluid temperature readings without restricting coolant circulation in modern LS V8 engines.
