When a car with an oxygen sensor is to be run on leaded fuel, the sensor should be removed to prevent clogging the sensor. When the sensor is out, plug the hole with this steel Blanking Plug. Fits standard 18x1.5mm oxygen sensor bungs.
This is the same plug as supplied with K&N Fuel/Air Ratio monitor kits, Part No.'s 3880 and 3881.
