Understanding the differences between an ignition coil and a spark plug is essential for car maintenance. This article delves into their unique roles in your vehicle’s ignition system.
What is an Ignition Coil?
The ignition coil is responsible for converting low voltage from the battery into the high voltage necessary to ignite the air-fuel mixture. It is usually located on top of the engine, connected directly to the spark plugs.
What is a Spark Plug?
The spark plug creates the actual spark that ignites the air-fuel mixture in the combustion chamber. Spark plugs are usually found threaded into the engine’s cylinder head.
Key Differences Between Ignition Coils and Spark Plugs
- Function: Ignition coils generate high voltage; spark plugs create the spark.
- Maintenance Frequency: Spark plugs require more frequent replacements compared to ignition coils.
- Location: Ignition coils are typically found on top of the engine; spark plugs are installed in the engine’s cylinder head.
When Should You Replace Them?
Both components should be inspected regularly. If you experience symptoms such as misfires or reduced fuel efficiency, it’s time to consider replacements. For information on when to replace both components together, visit our guide on when to replace ignition coils and spark plugs together.
