{"product_id":"weld-on-stainless-steel-o2-bung","title":"Weld On Stainless Steel O2 Bung","description":"\u003cp\u003eThe ISR Performance Weld-On O2 Bung is a stainless steel weld-in fitting threaded for 18mm x 1.5 sensors. The universal solution when you need to add an O2 sensor port: wideband installs, custom downpipes, or supplementing an exhaust that didn't come with a downstream bung from the factory.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eO2 bungs are the threaded fittings welded into exhaust piping that hold O2 sensors. The 18mm x 1.5 thread pitch covers most narrowband and wideband O2 sensors on the market (Bosch LSU 4.9, AEM, Innovate, NGK, and so on). Stainless steel construction holds up to the heat cycling and chemical exposure that would corrode mild steel bungs over time.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003eUniversal. Welds into any exhaust piping. Fits sensors with 18mm x 1.5 thread pitch. the standard for most aftermarket wideband and OEM-replacement narrowband sensors. Verify your specific sensor's thread spec before ordering. Common applications: custom downpipe builds, adding wideband bungs ahead of the cat, retrofitting a missing O2 location on an aftermarket exhaust (relevant for our IS-CSEXH-NC NC Miata exhaust, which doesn't ship with a bung).\u003c\/p\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e ISR Performance\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e IS-O2B\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eType:\u003c\/strong\u003e Weld-on O2 sensor bung\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 18mm x 1.5\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Custom downpipes, wideband install, missing O2 location retrofits\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eInstallation:\u003c\/strong\u003e Weld-in (TIG or MIG welding required)\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eSold:\u003c\/strong\u003e Individually\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 4px;\"\u003e\u003cstrong\u003eLegality:\u003c\/strong\u003e Off-road and competition use only\u003c\/p\u003e","brand":"ISR Performance","offers":[{"title":"Default Title","offer_id":45957112201413,"sku":"IS-O2B","price":16.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/2718\/9701\/files\/weldonbung__96055.1315984601.1280.1280__47840.1630073043.500.659.jpg?v=1773346766","url":"https:\/\/www.isrcompetition.com\/products\/weld-on-stainless-steel-o2-bung","provider":"ISR Competition","version":"1.0","type":"link"}
