M12 sensors - Install finger tight then 3/4 - 1 turn with wrench / O2 sensor socket 18ft. lbs. Flanged applications - (where flange is NOT already installed on sensor) Install flange to exhaust manifold first, then mount sensor in flange (A copper gasket is bonded to the flange & no additional gasket is required) Flanged applications - (where flange is already installedon sensor) (It is important to use the supplied gasket before installing sensor) Connect and route lead wire as originally installed
