Frequently Asked Questions

Will this eliminate my check engine light when I remove my O2 sensor?

The plug seals the port to prevent exhaust leaks, but some bikes may still throw a code. A tuner or fuel controller often needed to clear the error permanently.

Does this fit any V-twin motorcycle?

It fits standard V-twin O2 sensor ports. Verify your bike uses a standard port before ordering, as some custom or older V-twins may differ.

What's included?

The oxygen sensor plug only. No gasket or additional hardware is included.

Is this a permanent solution?

It's typically used as a temporary bypass during sensor removal or when a bike is running without an O2 sensor. Reinstall the sensor for full emissions compliance.
