Marine O2 Sensor Adapter Plate

150.00 - 345.00


Pictured is a custom made adapter plate for marine applications. An O2 sensor is used when converting an engine to electronic fuel injection and wanting to move from an “open loop” system to a “closed loop” system. The adapter plate installs in between the exhaust manifold and the riser/elbow allowing for the water jackets to still be in place and an o2 sensor to be installed in the still dry exhaust gasses.

Included with this item:

  • Custom adapter plate
  • (Optional) Gaskets for adapter plate * Due to varying stock we might not be able to provide the gaskets
  • (Optional) O2 sensor
