The spark plugs pictured are from a six cylinder in for a service. The vehicle actually had a misfire though the customer hadn’t noticed.
As the plugs were being removed they broke. We have no idea how long they had been in the vehicle and managed to extract five. The sixth was being incredibly stubborn so we decided to fit the five new ones.
We were then able to bring the engine up to temperature and tentatively attempt to remove the sixth plug.
Our little trick worked, the sixth plug was removed and this simple job restored the vehicle to being very smooth and responsive. The customer commented that it was like a different vehicle.
