Optimize Your Exhaust Airflow with Allstar Performance

Achieving accurate air-fuel ratio readings is critical for engine performance and longevity. The Allstar Performance 18mm O2 Sensor Bung (ALL34152) is engineered for custom exhaust fabrication, providing a secure, leak-free mounting point for your oxygen sensor. Featuring a 45-degree angled design, this bung allows for better clearance in tight engine bays where a standard straight bung might interfere with chassis components or drivetrain parts.

Key Features and Benefits

• Precision Fitment: Standard 18mm x 1.50 female thread compatible with most automotive O2 sensors.
• Durable Construction: Crafted from high-quality steel, designed for easy welding to mild steel exhaust piping.
• Angled Design: 45-degree orientation ensures optimal sensor positioning for accurate data logging and ECU tuning.
• Versatile Application: Ideal for custom header fabrication, exhaust system upgrades, and turbo manifold builds.

Whether you are building a custom race exhaust or replacing a damaged sensor port, this weld-on bung provides the structural integrity required for high-heat environments. Its natural finish allows for clean welding and can be painted or coated to match your exhaust system. Ensure your engine management system receives the most accurate data possible by installing high-quality components from GGCRACING.
