Replacement OPF Plug

The OPF plug fills the opening in the tubing where the sensor sits on a car with a gasoline particulate filter. Without the plug, exhaust gas leaks past the opening and on some cars a warning light comes on. If it goes missing or the thread is damaged, you order a new one here. Note the difference with the OPF cap: the plug goes into the opening, the cap closes it off on the outside.
