- Reduced engine performance
- Poor fuel efficiency and increased emissions

What are spark plugs?
Spark plugs are essential components in your engine, playing a crucial role in igniting the air-fuel mixture needed for combustion. Think of them as tiny, powerful devices that create a spark to ignite the fuel, powering your car's pistons and making the ignition system function.
A spark plug is located in the combustion chamber of the cylinder head and consists of a center electrode and a ground electrode. The center electrode is the small, metal protrusion at the center of the spark plug's tip, while the ground electrode is the metal piece surrounding it. When the spark plug creates a spark, it jumps between the center and ground electrodes, igniting the air-fuel mixture in the engine's cylinders to initiate combustion.
Here's how they work: Inside the engine's cylinders, the air-fuel mixture is compressed. When it's time to ignite, the spark plug generates an electric spark, igniting the mixture and causing a controlled explosion. This explosion pushes the pistons down, powering your car and setting it in motion.
Spark plugs come in various types: copper, iridium, and platinum. Each type has different durability and performance characteristics. Copper spark plugs are less expensive but have a shorter lifespan, typically around 20,000 to 30,000 miles. Platinum and iridium spark plugs are more durable, lasting anywhere from 60,000 to 100,000 miles or more, depending on the manufacturer and specific driving conditions.
Over time, spark plugs can wear out or get covered in deposits, affecting engine performance. Regular maintenance, such as replacing them according to your car's manufacturer recommendations, ensures efficient combustion, better fuel efficiency, and smooth engine operation.
When should I replace the spark plugs on my car?
You should replace the spark plugs on your car according to the manufacturer's recommended maintenance schedule, which can be found in your car's owner's manual. Generally, most modern vehicles require spark plug replacement every 30,000 to 100,000 miles, depending on the type of spark plugs installed and your driving habits.
Here are some common symptoms of faulty spark plugs:
- Poor engine performance
- Rough idling
- Engine misfires
- Difficulty starting
- Decreased fuel efficiency
- Reduced power
Set a reminder for yourself based on the mileage interval specified in your owner’s manual to ensure timely replacement.
