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.

Lucas
13 years of experience
Lucas was excellent. He was knowledgeable friendly; Lucas shared what he was doing to my car and why. I know a lot more about my car as a result of him coming to work on it. My Infiniti was a tall order: Lucas arrived at 11AM and stayed until about 5:30PM to finish. Upon completing the prescribed work, he showed me why a certain (previously insurmountable) issue was occurring, and asked to replace one final part. I said yes, after which Lucas made arrangements to go pick up the necessary part and return (he didn't leave until approximately 8PM). Then, the next day, Lucas contacted me again to let me know that a more updated of the part existed. He asked if we could schedule a time for him to come back and replace the part (ignition coil) one more time. Lucas goes the extra mile.

Shaun

What particularly impresses me about Shaun is the level of service and unwavering professionalism he displays. He understands that my knowledge about auto mechanics is next to nothing. He patiently works with me to identify my concerns, takes time to explain and offer solutions. The work that Shane does should be held up as an example for others to try to emulate. I believe that Shane deserves to be commended for his service which is always well beyond my expectations.
