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.

My 2007 Cadillac SRX AWD V6 was pinging on acceleration, had lost engine pep and the gas mileage had dropped to about 10 miles per gallon. The car has 97,000 miles on it and Cadillac recommends changing spark plugs at 100,000 miles. I called Cadillac and got a quote of $ 550. Wow! I called your mechanic and got a quote for $ 299.00. I asked for Patrick, who I had used before. Patrick came and and did a pretty involved job disassembling the top of the engine to reach the spark plugs and replaced them in about 3 hours. Patrick noted that the old plugs were very worn and that the spark plug tubes and the spark tubes had oil at the bottom of them. He told me that might be because the seal at the bottom of the spark plug tubes had failed, allowing oil from inside the valve cover to get into the spark plug tubes. I did some research and found that these seals failing is a relatively common issue in SRX's as well as other vehicles. The seals are not expensive but it appears that to replace them, the top of the engine would need to be disassembled again plus the valve cover on each side would also have to be removed, Then the seals could be installed and everything reassembled. That's most likely an expensive job. I drove the car after the new plugs were installed. Quite a difference. The car has its pep back, the mileage is starting to rise back to normal levels, and although I still get a slight ping at times, at this point it is about 90 % less than I was getting. My question is if I do nothing about the spark plug tube seals, will my issues return? Notes about this indicate that at some point the spark plugs are fouled enough to cause engine error faults and misfires if the spark plug tube seals are not replaced. Now I have to decide if I want to spend the money to have the new seals installed or take my chances and see what happens. If you read this Patrick, I would appreciate your best guess. Patrick is a very good mechanic. My dad ran an auto parts store, a garage and a machine shop for 25 years so I do know a few things about cars and know a good mechanic when I see one. If you need an excellent mechanic who is also honest, look no further than Patrick.
