Bikers Choice O2 Sensor Plug 18MM X 1.5 Ea

This Bikers Choice O2 sensor plug is made from steel and features a chrome finish, with an internal Allen head for a clean look when installed. It's designed to fit an 18mm x 1.5 thread size, which is common for many exhaust systems. If you've modified your exhaust or are doing some custom tuning, you might end up with an extra O2 sensor bung that you no longer need. This plug is the perfect solution for securely sealing off that opening.

Using this plug ensures that exhaust gases aren't leaking out of unused bungs, which can affect your engine's air-fuel ratio readings and potentially throw off your tune. The internal Allen head means you won't have a visible hex head sticking out after installation, keeping the appearance of your exhaust system tidy. It's a well-built part that does exactly what it's supposed to do, making sure your exhaust system is properly sealed.
