MagnaFlow Oxygen Sensor Bungs

When you're doing a custom installation, or if you want to do a show-quality job with no compromise in quality, fit or finish, MagnaFlow oxygen sensor bungs are just what you need. These fittings provide a designated location to install an oxygen sensor within an exhaust system, allowing it to accurately measure the oxygen content in the exhaust gases and send that information to the engine control unit (ECU) for optimal fuel delivery and emissions control. Bungs can be either threaded (screwed into the exhaust) or weldable (welded directly into the exhaust pipe), depending on the application. Selecting the correct bung fitting requires matching the thread size to the specific oxygen sensor that you are using. Order the oxygen sensor bungs designed for your project's application needs.
