Product Details

This is a Twin Power O2 sensor plug, measuring 12mm by 1.25. It's designed to seal off an exhaust port where an oxygen sensor used to be, or where one isn't needed. This helps prevent exhaust leaks and keeps your engine's air-fuel mixture readings accurate by ensuring no extra air gets in or exhaust gas gets out through an open port.

This plug is sold individually, so you can buy exactly the number you need for your specific application. It's a straightforward part that does its job reliably, ensuring a clean seal on your exhaust system.
