High Spark ignition coil. It's the Sport version (not the Premium). Used for about 50,000 kilometers. It was running normally without any problems until I removed it, but I don't know when its lifespan will end. Torque will increase. Regarding spark plugs, aftermarket ones are recommended against as they can cause problems, so genuine ones are recommended. If you wish, I can also include used genuine spark plugs. Thank you.
