How do I change the spark plugs in my Ford Mondeo?

I've noticed my Ford Mondeo seems to be lacking some power and the engine seems to be running rough. I suspect it might be time to change the spark plugs. How do I go about doing this?

First, make sure you have the correct tools and replacement spark plugs. Start by locating the spark plug wires and gently pulling them off the spark plugs. Use a spark plug socket and extension to remove the old spark plugs. Check the gap on the new spark plugs before installing them. Then, carefully torque them to the recommended specifications. Make sure to replace the spark plug wires in the correct order.

Another important step is to replace the spark plug wires if they are worn or damaged. This can greatly affect the performance of your Ford Mondeo's engine. Also, consider upgrading to high-performance spark plugs for a better overall driving experience.

Don't forget to disconnect the negative battery terminal before starting the spark plug replacement process!
