Kooks Headers Oxygen Sensor Extensions

Kooks oxygen sensor extensions are special pipe fittings designed for adding an O2 sensor in any location where you need one. They are great for custom exhaust, headers, or downpipes, or for adding an extra air/fuel sensor for use with a wideband. Made of quality stainless steel, these threaded fittings will not rust, and allow replacement of a just the damaged fitting itself, without having to replace the entire exhaust component. Save the pipe and replace that faulty bung fitting with a Kooks weld-on oxygen sensor extension replacement—they're the perfect repair-friendly solution.
