What is the spark plug model for the Spirior?

[VonBrielle]

ILZKR7B-11S5787 is the original spark plug for the Spirior. Spark plugs are installed on the side or top of the engine. In early models, spark plugs were connected to the distributor via ignition cables, but over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. Steps to replace spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris such as leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage ignition wires in the correct firing order, then secure the cover.
