What is a spark plug?

A spark plug is a crucial component of your vehicle’s ignition system. It creates the spark needed to ignite the air-fuel mixture in the engine's combustion chamber, enabling the engine to start and run smoothly.

How do I know when my spark plugs need to be replaced?

Common signs that your spark plugs need to be replaced include:

  • Difficulty starting the engine
  • Rough idling or misfiring
  • Poor acceleration
  • Decreased fuel efficiency
  • Engine knocking or pinging sounds

How often should spark plugs be replaced?

The replacement interval for spark plugs varies depending on the type of plug and the manufacturer’s recommendations. Generally, conventional spark plugs should be replaced every 20,000 to 30,000 miles, while platinum or iridium spark plugs can last up to 60,000 to 100,000 miles.

Can I replace spark plugs myself?

Yes, replacing spark plugs can be a DIY task if you have basic mechanical skills and the right tools. However, it’s important to follow the vehicle manufacturer’s guidelines and use the correct type of spark plug for your specific engine.

What happens if I don't replace my spark plugs?

Failing to replace worn spark plugs can lead to various engine issues, including:

  • Poor engine performance and reduced power
  • Increased fuel consumption
  • Difficulty starting the vehicle
  • Potential damage to the ignition system and catalytic converter

What are the different types of spark plugs?

There are several types of spark plugs, including:

  • Copper Spark Plugs: Offer good performance at a lower cost but have a shorter lifespan.
  • Platinum Spark Plugs: Provide better durability and efficiency than copper plugs.
  • Iridium Spark Plugs: Offer the best performance, longevity, and fuel efficiency, making them ideal for modern engines.

Can spark plugs improve my vehicle’s performance?

Yes, high-quality spark plugs can improve your vehicle’s performance by providing better combustion efficiency, which leads to smoother engine operation, improved fuel economy, and reduced emissions.

How can I check my spark plugs?

To check your spark plugs, you need to:

  1. Remove the spark plug wire or ignition coil.
  2. Use a spark plug socket to remove the spark plug.
  3. Inspect the electrode and insulator for signs of wear, fouling, or damage.
  4. Check the spark plug gap with a feeler gauge and adjust if necessary.

What is spark plug fouling?

Spark plug fouling occurs when deposits build up on the spark plug electrodes, causing poor ignition performance. Common causes of fouling include:

  • Running rich fuel mixture
  • Oil leaks into the combustion chamber
  • Using the wrong heat range spark plug

Can bad spark plugs cause engine misfires?

Yes, bad spark plugs can cause engine misfires by failing to ignite the air-fuel mixture properly. This can lead to rough idling, poor acceleration, and increased emissions.

How much does it cost to replace spark plugs?

The cost to replace spark plugs varies depending on the type of spark plug and labor costs. On average, spark plug replacement can range from £50 to £150, with higher-end iridium plugs and labour charges potentially increasing the cost.

Do I need to replace all spark plugs at once?

Yes, it’s recommended to replace all spark plugs at once to ensure consistent performance and avoid uneven wear across your engine’s cylinders.
