Spark Plug Replacement Service & Cost

What are the Spark Plugs all about?

The spark plugs are an important part of the ignition system. When you turn the ignition key (car's key) on, it causes the ignition coil to generate the spark which ignites the air-fuel mixture in the engine cylinders to start the engine. The number of spark plugs in the car is the same as the number of cylinders, although some vehicle manufacturers will use two spark plugs per cylinder.

Over time, the spark plugs wear out and require replacement. When the spark plugs wear out, it is harder for it the air-fuel mixture to ignite, resulting in engine misfires. If one of the spark plugs has failed, the car will still start and run, but it will run poorly. On some vehicles, spark plug replacement may be labor intensive and involve removal of the intake plenum.

Keep in mind:

  • When the spark plugs are replaced, it is a good idea to inspect the ignition cables as well.
  • Spark plugs come in numerous ratings, and the correct rating for your vehicle should always be used.

How it's done:

  • Scan the car for codes.
  • Clean all surface areas around the spark plugs.
  • Remove spark plugs.
  • Inspect threads in engine head (where plugs are installed).
  • Perform compression test if needed.
  • Inspect ignition wires.
  • Apply anti-seize to the threads of the spark plugs.
  • Install new spark plugs.
  • If needed replace any gaskets removed.

Our recommendation:

During routine maintenance and checkups, your ignition system should always be inspected. Any time that a component of the ignition system is replaced, it’s a good idea to consider replacing the spark plugs as well. If you don’t preemptively change your spark plugs your engine will let you know by misfiring or running poorly, so schedule an inspection as soon as you notice that your engine is not performing properly.

What common symptoms indicate you may need to replace the Spark Plugs?

  • Check Engine light is on.
  • Engine misfires.
  • Poor fuel economy.
  • Vibration coming from the engine.

How important is this service?

Spark plugs are responsible for igniting the fuel that your engine uses to run. When you turn your key, a small voltage of power is sent to the ignition coil, where it is transformed into high voltage currency. This high voltage currency is sent through the ignition cables to the spark plugs. The spark plugs use the power to create a spark, which ignites the fuel, and allows the engine to function.

When the spark plugs malfunction, this spark won’t be created, and the fuel will not be ignited as it should. Your vehicle has many spark plugs, so depending on how many fail, your engine may either run poorly, or not run at all. Continuing to drive a vehicle with malfunctioning spark plugs can also cause damage to the catalytic converter.

I had taken my car to firestone who over charges drastically. They also lost my tire lock. Lucky enough, Chet had the tool with him to take the keys off! So I got new sets for my tires for free because firestone lost mine and I got to have my brakes done! Thank you for your smart thinking! My brakes are working great!

Joseph is honest and very knowledgeable. He arrived on time and finished really quickly. He even took the time to explain what happened and how to prevent it from happening again. He also walked me through some issues that might need my attention and his honest opinion on what can wait. I was really impressed and I would definitely recommend and use Joseph and YourMechanic again.

Choeun arrived early and ready to work. He was very nice, courteous and knowledgeable about the repair. He got set up and started the repair, upon removing the alternator he found that the part he had brought was different and could not be used. Before letting me know what happened, he had already called the local Autozone and confirmed that they had the part in stock and kept it on hold for me. He explained to me how the invoice price would be adjusted so I never had any worries. He made everything easy and seamless. He answered all my questions and concerns honestly and had many helpful tips for my cars maintenance. Due to Choeuns professionalism and the fact that he went above and beyond to help make the repair successful I would high recommend him as well as this service.
