AEM No-Weld O2 Sensor Mounts – 3.25 to 3.5 inch Diameter – Universal
If you need to mount an O2 sensor and don’t know how to weld or can’t find someone who can, this is a permanent solution that replaces a weld in O2 bung. Simply drill a hole in the exhaust, install the gasket, and bolt the clamp. It’s that easy to install and all you need to do in order to add a wideband to your car!
