Weaponr catalog Weaponr calendar


  • Enables installation of an O2 sensor into headers or custom exhaust
  • Necessary for closed loop fuel injection systems
  • Convenient for dyno testing
  • Welds in to the pipe
  • Made of high grade stainless steel
  • Threaded for O2 sensor

Most modern electronic fuel injection systems are "closed loop" systems that rely on feedback from an oxygen sensor to regulate the air/fuel ratio. The oxygen sensor threads into a bung on the factory exhaust pipe where it can read the oxygen content of the exhaust gas. But what if you remove the factory part and install headers or a custom exhaust system? Where and how do you attach the O2 sensor? Weapon-R has the solution with this handy O2 sensor bung. Just choose where you want to install the sensor, cut a hole and weld the bung in place. It’s threaded for most popular sensors and it’s made of stainless steel, so rust won’t be an issue.
