Chevrolet Tahoe - Spark Plugs - Seattle, Washington
Noe was very knowledgeable and worked fast and efficiently. There were some confusion in the beginning on the service, but that was due to YM's website's limitations, or my inexperience with using their appointment booking system, than anything involving my experience with Noe. I've booked a follow-up repair appointment with Noe. YM represents good value and convenience. I would definitely use Noe and YM again in the future.
Mercury Grand Marquis - Spark Plugs - Seattle, Washington
Noe is a good mechanic. He worked on my 1985 Mercury Grand Marquis. He is knowledgeable and competent. He answered my questions and offered good advise on my car's maintenance. He allowed me to observe him servicing my car. He was friendly and polite. I will use his services again in the future! A+

Ford Taurus - Spark Plugs - Seattle, Washington
Robert Was great, he came and got right to it. After all was said and done he ran me through what he did and the price breakdown. I would go with Robert again. The 'yourMechanic' service was not as great, but this has nothing to do with Robert - if they (customer support) start to jerk you around, I'd suggest asking for a supervisor and for a compensation... However as I've said, it had nothing to do with Robert, he was awesome, 10/10 would deal with him again. Finished faster than originally quoted and final price reflected that.
GMC Envoy - Spark Plugs - Seattle, Washington
Aside from a late arrival which wasn't communicated, all around great experience. Robert mentioned he wasn't allowed to contact the customer, which is a shame as YourMechanic couldn't provide me clear insight to arrival. Robert was quick but thorough with the spark plug change, would recommend him.

Casey is awesome. He showed up on time and described in detail what he was going to do. He was very professional and cleaned the area when he was done. Highly recommend Casey and YourMechanic.
Subaru Forester - Spark Plugs - Seattle, Washington
I am so happy about my experience with yourmechanic.com. Casey was very knowledgeable, communicative, and professional. The cost of the work done was much lower than what I had been quoted at the repair shop. One thing I especially liked about Casey, was that he seemed real about what needed to be done ASAP and what I could work on at a later date. With other places, I feel like they word things in an alarming matter to try and get me to do it all at once, which I'm just not able to afford. I hope I have more experiences like this, as I will be booking all of my work through yourmechanic.com from now on! Thank you!

Spark Plug Replacement Service

What are spark plugs and how do they work?

Spark plugs are one of the key components of your vehicle’s ignition system. They ignite gasoline and air inside of your engine. This gives your engine the power to propel you down the road. The spark plug takes high voltage electricity from the ignition coil and creates a spark at just right moment during the engine’s combustion cycle. This gives the engine the best mix of power, fuel economy and low emissions. However, the electrode at the end of the spark plug eventually wears out and can cause performance issues.

Spark plugs-MATROX-1

When should you replace spark plugs?

Replacement should follow the vehicle maintenance schedule. This will be listed in the vehicle’s owner’s manual. Some cars require regular replacement at 30k, 60k or 100k miles. It is possible in some cases that a spark plug might fail before the service schedule, but it’s not typically common.

Avoiding spark plug replacement can cause:

  • Difficulty starting your car.
  • Check engine light for a misfire code.
  • Flashing check engine light during acceleration for misfire, this can cause engine damage.
  • Reduced fuel economy and/or power.
  • Rough idle and/or unexplained engine vibration.
  • Failed State emission testing.

Even if only one spark plug is found to be faulty, they should always be replaced in sets. Most engines will require 4,6, or 8 spark plugs.

How do mechanics replace spark plugs?

Spark plugs are threaded into the engine’s cylinder head(s). Most cars have one plug per cylinder, so a four-cylinder engine will have four plugs, a six-cylinder engine will have six plugs, and so forth. The mechanic will:

  • Have the correct spark plugs on hand for your vehicle
  • Pull any diagnostic trouble codes that may be related to worn spark plugs.
  • Remove the original spark plugs and look at removed spark plugs for any clues indicating engine mis-operation exists; such as oil burning, excessively rich mixture, pre-ignition damage etc. Inform owner of any found unusual conditions.
  • Install new plugs using a torque wrench.
  • Finally, a road test of the vehicle to confirm normal operation.

Is it safe to drive with worn spark plugs?

Yes, but spark plugs that are worn enough to cause engine-misfiring have the potential to cause engine damage and overheating of the catalytic converter. Regardless of the age of the plugs, or mileage, if the engine misfires or runs poorly, the plugs should be inspected for defects. Generally, spark plug failure will not keep the engine from running, but in cases of extreme wear, you may experience a limitation in the speed at which you can drive the car. If the maintenance schedule says the plugs should be replaced, it is best to do so promptly.

When having spark plugs replaced keep in mind:

  • High-speed driving may accelerate spark plug wear. Consider earlier than required inspection and tune-up if you operate the car in severe conditions.
  • Plugs should always be promptly replaced per the manufacturer maintenance schedule even if they appear to be working perfectly.
  • If your vehicle is equipped with spark plug wires (as opposed to a coil-on-plug system), the wires should be replaced at the same time. This may increase the cost of your repair.
  • It is possible that when doing a spark plug replacement, your vehicle may also need additional parts like ignition coils, this will add to the repair cost.
  • Some engines require that the intake manifold be removed while replacing spark plugs. This may increase the parts and labor cost for the repair.
  • Leaking valve cover gaskets, which have let oil get in contact with the spark plugs, coils or wires, may be the cause of ignition system issues. Valve cover gaskets will need to be replaced in addition to the spark plugs, wires or coils. This will add to the repair cost.
