An exhaust port gasket is adapted for insertion between an engine exhaust port and an exhaust pipe flange for sealing therebetween. The gasket includes at least one primary aperture acting as an exhaust port for accommodating flows of exhaust gases, and includes at least one electronic oxygen sensor responsive to oxygen levels of gases passing through the exhaust port. To the extent that oxygen-sensing is provided at the exhaust port, improved real time engine management may be derived from cylinder-by-cylinder measurements of the oxygen levels by inputting the measurements into an engine control unit module to optimize engine performance parameters, including fuel economy and emissions levels. In one described embodiment, a plurality of cylindrical oxygen sensor probes are positioned in surface grooves of a spacer layer of the exhaust gasket, and individual probe sensor wires are collectively connected to a wire harness portion of the gasket.
