For everyone who wants to use an electronic oil temp sender with an American thread (such as AutoMeter), this adapter plug is for you. We start with an OEM Subaru drain plug and machine an 1/8"-27 NPT female thread in it. The rear of the plug is machined for maximum oil coverage. The plugs are tested to exceed OEM torque specifications for standard applications. Replaces stock oil drain plug in original location. Includes new gasket. Sender not included.
