30 Degree Angled Oxygen Sensor Weld Bung (M18 x

The 30 Degree Angled Oxygen Sensor Weld Bung (M18 x 1.50) from VIBRANT PERFORMANCE is a precision fabrication component engineered for custom exhaust manifold and header builds. Designed for mechanics and fabricators who are integrating oxygen sensors into custom or modified exhaust systems, this weld bung provides a clean, professional mounting point that allows proper sensor placement and signal accuracy. Whether you're building a turbo manifold, supercharger exhaust, or completely custom headers, this component eliminates the need for makeshift sensor mounts that compromise data integrity and longevity.

The 30-degree angle is critical for sensor optimization—it positions the oxygen sensor perpendicular to exhaust gas flow, minimizing thermal shock and turbulence effects that degrade sensor readings and lifespan. The M18 x 1.50 metric thread pattern is the industry standard for wideband and narrowband oxygen sensors, ensuring compatibility across most performance and OEM applications. Manufactured to VIBRANT PERFORMANCE's exacting standards, the bung is ready for MIG or TIG welding onto your fabricated manifold or header tubes, with the angled design providing optimal clearance for sensor installation and removal without interference from nearby components.

This component is essential for anyone serious about custom exhaust fabrication, engine tuning, and data logging. Custom car builders, performance shops, and DIY enthusiasts who demand accurate air-fuel ratio feedback will appreciate the proper engineering this bung brings to the table—no more improvised bungs that crack, leak, or rattle loose during high-performance driving. Installation requires basic welding skills and proper fixture support; once welded and cooled, it provides a rock-solid platform for your oxygen sensor, ensuring reliable signal transmission to your engine control unit or standalone tuning system for years of boost and revs.
