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 bmw 325i failed the smog check and there was a engine cylinder 4 misfire. Honorio did an excellent job of fixing both spark plug and coil and immediately huge difference in the engine idling,no vibrations.. He also gave me v good advice to run car for atleast 100 miles as smog detection would not get faulty old code. I had a nice relaxing afternoon sitting by pool and thank Honorio for fixing the car. Total cost $350.00

For the better part of a month, I’d been panicking over my 2002 BMW 330ci, which had basically lost all power, so it was just sitting in my garage. Towing it to a shop for diagnostic testing was an option, but then I’d be stuck in the event projected repair costs exceeded the car’s worth (or even half of its worth). Being stuck sucks, so I decided on exercising another option. After reading a bunch of reviews and doing some research on Your Mechanic and their team of mechanics, I decided on giving them a try. I am so glad that I did. What an outfit! Great concept, great execution ... The people in the office are wonderful at keeping you informed, answering questions, from beginning to end. Their online presence and transparency dismisses any weirdness customers may feel about the whole inviting strangers over thing, too. And Your Mechanic delivers, by connecting top-tier mechanics with people who need their help. That’s exactly what Your Mechanic did for me, by introducing me to Chris M. He came to my rescue. What a pleasant polite young gentleman, Chris is. And Boy oh boy!, does he know his stuff! With patient professional confidence and calm, Chris ably diagnosed my car’s problems, tested the hypothesis, and retested too. The problems weren’t easy to find or common whatsoever. Thanks to diligence and expertise, however, Chris M. identified the issues. It wasn’t piston rings or the catalytic converter, as I’d feared, but a faulty engine coil. Chris explained the issue, actually showed me what was going on in the engine compartment, provided me with a detailed quote that I knew was fair and reasonable (talk about a mind Blow!), and then he even offered to come back and do the work, if I wanted. Heck Yes! Chris came back the very same day to render the fixes, all from inside of my garage. No tow trucks, no queue of customers waiting, no worries about surprisingly huge repair bills, and no concern about strangers coming over, or anxiety about non-OEM parts. I have a brand new engine coil, new spark plugs, a clean gas line, clean oil – and a renewed confidence in my automobile’s reliability. Presto! My car runs like a charm. Chris M. earned my confidence, my trust, and my respect – and that’s an amazing feat. Having a qualified, knowledgeable professional come to my home, diagnose my car’s troubles, and even render repairs on site, using manufacturer-recommended parts, sounds like a luxury I couldn’t afford. Turns out I was wrong. No doubt, from here on out, I will be recommending Chris M. and Your Mechanic to anyone and everyone.
