Spark Plugs

Each spark plug in your vehicle's engine performs a key function. Spark plugs ignite the mixture of air and fuel in the combustion chamber to create power for your engine to run the car. Sparks plugs may look simple in terms of their design, but without them, your car would go nowhere. They produce an electric spark inside your Mazda's cylinder head. Aside from assisting in initiating the combustion process, spark plugs also help in dissipating the heat produced in the combustion chamber. For the spark plug to fire properly, it requires a voltage of more than 20,000 volts. However, continued use of the engine can cause them to wear out and cease to produce the right amount of voltage. You can tell if your spark plugs are bad by checking for various signs, including difficulty in starting your car, reduced car performance, poor fuel economy, and knock-like noises. Other symptoms of a failing set of spark plugs are lack of acceleration, reduced gas mileage, engine misfires, rough idling, and hard starts. It's important to replace spark plugs when they start to fail so your engine can run at peak performance. Always insist on using genuine Mazda replacement spark plugs.
