Spark plugs in a Mitsubishi 3000GT need to be replaced every 30,000 to 60,000 miles for optimal performance. The spark plugs in a Mitsubishi 3000GT needs to be inspected and cleaned every 10,000 to 15,000 miles. Your previous owner may have had more miles on it. Check it with an automotive technician and replace the spark. Replacing the spark plugs extends the engine's life and enhances fuel efficiency.
