Swapping out plugs on the X1. This is the shiniest spark plug hole I’ve ever seen. Little bit if carbon deposit came out when I pulled the plugs which I guess is to be expected from an 87k DI engine. She’s still running smooth though. Other than having to get a special spark plug tool and having to remove the cabin filter valence, it was a very easy job. Each plug came out with ease. Ugly N20 for your time.
