{"product_id":"o2-bung-mild-steel","title":"O2 Sensor Bung – Mild Steel or Stainless","description":"\u003cp\u003eThe O2 Sensor Bung, available in either mild steel or stainless, is designed for adding an oxygen sensor port to your exhaust system during fabrication or modification. Built from weldable mild steel, this bung is easy to integrate into custom exhaust setups, making it a go-to solution for builders working on performance, off-road, or street applications.\u003c\/p\u003e\n\u003cp\u003eWith a standard M18 x 1.5 thread, this bung is compatible with most factory and aftermarket O2 sensors. It can also be paired with an O2 bung plug when a sensor is no longer needed, allowing you to cleanly seal the port without leaving an open hole in your exhaust.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Mild Steel or Stainless O2 Sensor Weld-In Bung\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 14 14\" height=\"14\" width=\"14\"\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M2.75 7H11.25\" class=\"vertical\"\u003e\u003c\/path\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M7 2.75L7 11.25\" class=\"horizontal\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Mild steel or stainless\u003c\/li\u003e\n\u003cli\u003eThread Size: M18 x 1.5\u003c\/li\u003e\n\u003cli\u003eWeld-in design for custom exhaust systems\u003c\/li\u003e\n\u003cli\u003eCompatible with standard O2 sensors\u003c\/li\u003e\n\u003cli\u003eCan be used with O2 bung plugs\u003c\/li\u003e\n\u003cli\u003eEasy to weld and fabricate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 14 14\" height=\"14\" width=\"14\"\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M2.75 7H11.25\" class=\"vertical\"\u003e\u003c\/path\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M7 2.75L7 11.25\" class=\"horizontal\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal exhaust fabrication\u003c\/li\u003e\n\u003cli\u003eFactory and aftermarket exhaust systems\u003c\/li\u003e\n\u003cli\u003eOff-road vehicles and rock crawlers\u003c\/li\u003e\n\u003cli\u003eRace cars and performance builds\u003c\/li\u003e\n\u003cli\u003eLS and LT engine exhaust systems\u003c\/li\u003e\n\u003cli\u003eAny application requiring an O2 sensor port\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e\n\u003cdetails class=\"details\"\u003e\n\u003csummary class=\"details__header\"\u003e\u003cstrong\u003eTech Insight\u003c\/strong\u003e\u003cspan class=\"svg-wrapper icon-plus\"\u003e\u003csvg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" fill=\"none\" viewbox=\"0 0 14 14\" height=\"14\" width=\"14\"\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M2.75 7H11.25\" class=\"vertical\"\u003e\u003c\/path\u003e\u003cpath stroke-linecap=\"round\" stroke-width=\"var(--icon-stroke-width)\" stroke=\"currentColor\" d=\"M7 2.75L7 11.25\" class=\"horizontal\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"details-content rte\"\u003e\n\u003cp\u003eO2 bungs provide a secure, leak-free mounting point for O2 sensors, ensuring accurate readings for tuning and engine management.\u003c\/p\u003e\n\u003cp\u003eIf you plan to remove the O2 sensor later, pairing this bung with a matching M18 x 1.5 bung plug allows you to seal the system without reworking the exhaust.
