Product Details

The Moroso 22731 oxygen sensor bung is a weld-in fitting designed for custom exhaust systems and headers that require the addition of an O2 sensor port. This precision-machined bung allows you to install oxygen sensors in exhaust pipes where factory provisions are not available.

Key Features:

  • M18 x 1.5 metric thread size - fits most modern oxygen sensors
  • Weld-in design for permanent, leak-free installation
  • Precision-machined steel construction for durability
  • Allows installation of wideband or narrowband O2 sensors
  • Essential for custom exhaust fabrication and tuning applications

This bung is ideal for racers, performance enthusiasts, and custom exhaust builders who need to add oxygen sensor ports to exhaust systems for proper air-fuel ratio monitoring and engine tuning. The M18 x 1.5 thread is the standard size for most modern automotive oxygen sensors including Bosch LSU 4.9 wideband sensors and many OEM narrowband sensors.
