How do I check the spark plugs in my Vauxhall Zafira Life?

I recently purchased a used Vauxhall Zafira Life and I want to ensure that the spark plugs are in good condition. Could you please provide me with step-by-step instructions on how to check the spark plugs? Thank you!

First, locate the spark plug wires at the top of the engine. Gently pull each wire off and use a spark plug socket to remove the spark plugs.

You can also use a spark plug tester to check for any signs of wear or damage on the spark plugs. If you notice any issues, it's best to replace them.

Make sure to check the spark plug gap using a feeler gauge. Refer to the owner's manual for the correct gap measurement and adjust if necessary.

Once you have checked the spark plugs, reinstall them and reconnect the spark plug wires. It's always a good idea to replace the spark plugs every 30,000 miles for optimal performance.
