One simple way to proactively protect your engine is by changing the spark plugs and wires. The wires running from your distributor send an electrical current to the spark plugs which then generate a spark to ignite the fuel and air mixture in your cylinders. They get a lot of use and they can cause your engine to run really rough if they get too old.

Changing the plugs and wires is typically not a difficult procedure and can be done with little investment in both time and money. Most manufacturers recommend changing them every 30,000 miles (48,280 kilometers), but some can go a little longer. When you change your engine's spark plugs make sure to change the wires at the same time to ensure you're getting the best electrical current to the plugs. If you change the plugs and wires regularly, your engine will love you for it. It's a move that'll keep your engine firing consistently and your gas mileage up at the same time.
