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.

Tien

Mr. Phan was early to his appointment and fixed front and back brakes while my car was parked at work in about an hour. He was very polite and professional and now my brakes do not squeek when I apply pressure. He was so honest he told me my back brakes did not need to be replaced but I told him to do it anyways because I thought it was a good idea since I have never replaced them since I have owned my car. This is my second time using mobile mechanic and I am very pleased with the pricing structure and level of professionalism. I would definalty reccomend this service to my friends and family.

Timothy
17 years of experience
Timothy was terrific, highly knowledgeable and very personable. I had scheduled an appointment to have my daughter's O2 sensors replaced, but after he got here and assessed the situation, he said that we didn't need them replaced. He cleaned out a few areas that might have been causing the problem which reset the check engine light. I didn't get charged for anything except a diagnostic and the gas treatment he put in the car. The repair shop we had originally checked with had said the sensors needed replacing and quoted us $400 to do so and I'm sure if we had gone there instead of with Timothy, they would have been replaced without actually fixing the problem. Timothy was up front about everything he was doing in the car and gave us a list of possible upcoming maintenance items. I loved the service and will definitely use it again.
