Should I replace my Volkswagen Golf's spark plugs?

I have a Volkswagen Golf and I am wondering if I should replace my spark plugs. They have not been replaced for a couple of years and the car is starting to feel sluggish. Is it necessary to replace them or can I wait a bit longer?

Yes, it is recommended to replace your spark plugs every 30,000 miles. As they wear out, they can cause issues with your engine's performance.

If your car is starting to feel sluggish, it could be a sign that your spark plugs need to be replaced. I would suggest replacing them sooner rather than later.

You can wait a bit longer, but it's better to replace them sooner rather than later. Worn out spark plugs can cause reduced fuel efficiency and can even lead to engine misfires.
