The kit includes an adjustable bracket and an M18x1.5 threaded port that accepts most wideband O2 sensors. It’s designed for straightforward retrofit use on compatible exhaust tubing and comes with a removable spacer adapter to protect sensor tips.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the clamp-on design simplify installation?\u003c\/h3\u003e\n\u003cp\u003eThe clamp-on construction eliminates the need for welding, so you can add a sensor with common garage tools. After drilling a correctly sized hole in the pipe, the bracket clamps around the exhaust and secures the threaded bung in place, reducing time and specialized labor.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 2-1\/4\"–2-1\/2\" exhaust outer diameters via adjustable bracket\u003c\/li\u003e\n  \u003cli\u003eRequires only a 13\/16\" hole and basic hand tools\u003c\/li\u003e\n  \u003cli\u003eNo welding or cutting beyond the drill hole\u003c\/li\u003e\n  \u003cli\u003eIncludes bolts, nuts, crush washers, flanges and an exhaust gasket for assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this adapter prevent exhaust leaks around the sensor?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes sealing components and a spacer adapter to minimize leaks when installed properly.
