Spark plugs are small, and most drivers are completely oblivious to the fact that they even exist. But the truth is, spark plugs serve a vital purpose in keeping your car moving. Here’s what you should know before brining your car to a Spring Hill auto repair shop.
What Exactly Are Spark Plugs?
Spark plugs play an important role under the hood of your car. Composed of a shell, insulator, and central conductor, spark plugs create the tiny surge of electricity that generates the combustion necessary to start your car. Once your car engine’s pistons are in motion, your car turns on and stays powered to burn fuel and keep you moving.
Due to their nature, spark plugs thrive on heat. They can withstand a great deal of pressure and are even designed to burn off fuel deposits and contamination residue. The bottom line is that your car won’t move so much as an inch without properly functioning spark plugs.
Why Do Spark Plugs Need to be Replaced?
Spark plugs that are weak or in bad condition can leech their health problems to the rest of your car, just like an infection in the body. It might start with misfires during acceleration or trouble starting your car in the cold, but the problems will grow to include poor fuel economy and the inability to sustain high speeds.
Though spark plugs can last anywhere between 30,000 and 120,000 miles and endure impossibly high temperatures, they eventually wear down. The interaction between air and fuel can cause pre-ignition of the fuel, which translates into a very jerky ride for you as your car struggles to maintain a consistent supply of energy. Also, given that the spark plug’s electrical ignition must travel across a small gap to generate combustion, age has a tendency to expand that gap and make it more difficult for combustion to occur.
What Are the Signs of Dying Spark Plugs?
As mentioned above, your spark plugs are likely dying when your vehicle experiences hard starts on a regular basis for a Spring hill tune up check This means that starting your car feels jerky and disjointed, and may be accompanied by knocking noises that sound like misfires. It’s also likely that your car won’t perform as well when driving—like your car is fatigued and just can’t muster up the energy to keep moving forward.
When you bring your car to the right mechanic, spark plug replacement is simple, affordable, and rewarding for you and your car alike!
