Spark Plugs Need to Be Replaced Periodically

That little engine part called the spark plug performs a huge job in delivering a vehicle's power, performance, dependability and fuel efficiency and, according to the non-profit Car Care Council, should be replaced periodically.

"Spark plugs are one of the hardest working parts of a vehicle. A spark plug can fire 400 times per minute per cylinder or 1,600 times a minute on a four-cylinder engine," said Rich White, executive director, Car Care Council. "Many car owners delay spark plug repair on their vehicles, even after they have failed. This is a mistake since fouled, damaged or worn out spark plugs can lead to engine damage, reduced fuel efficiency and poor performance like misfiring, hard starting and sluggish acceleration."

If you spot any of the following symptoms, the Car Care Council recommends having your vehicle checked to prevent more costly problems from developing.

  • Rattling, pinging or knocking noises. When spark plugs begin to misfire, you may notice unusual noises from the force of the pistons and combustion not working properly. Pistons travel at high velocities; if the spark plug fires at the wrong time, this could lead to constant rattling, pinging or knocking sounds.
  • Hard vehicle start. If your car is having trouble starting or just feels disjointed and jerky, your spark plugs may not be working right. This can lead to misfires and erratic performance.
  • Reduced performance. Spark plugs fire when you accelerate and change gears. If the spark that the plug generates isn't functioning at 100 percent, your vehicle performance will be poor, and you'll experience a sluggish and fuel-wasting drive.
  • Poor fuel economy. Lots of things can lead to poor fuel economy. In the case of old spark plugs, fuel is wasted because your vehicle fails to receive the proper, heat-generating spark at the right time.

The Car Care Council recommends that consumers consult their owner's manual for the vehicle manufacturer's recommended spark plug replacement intervals. The council also recommends replacing all of the plugs at the same time and with the same type of spark plug that the vehicle was originally equipped.

"Replacing spark plugs is a relatively inexpensive maintenance task and can be performed by a do-it-yourselfer or by a professional technician at any auto repair shop," said White.

Bert & associates are awesome. I started servicing my BMW couple years back. They are now my default repair shop for all family vehicles. When service is required, it's expertly provided. Perhaps more important, when work is unnecessary or minimally resolved, they explain why, to quickly get me back on road. I always leave the shop feeling work is thorough with safety in mind. Clean shop, clear talk, trustworthy service...all at a fair price.

I came in to get a car inspection and I was able to be seen immediately! Bert even gave me a great deal on the inspection since it was my first time. I will be back for all of my car needs!

reviewiconHighly Recommended, Honest Business
Heating and Cooling Services, near Concord, NC

I was referred here by another mechanic to help out with my A/C. I told the owner, Bert Jones that I was getting rid of my car in the fall and did not want to spend a lot of money. I only wanted the A/C charged and a sealant put in hoping it would last the summer. I was very impressed that my wishes were respected and no one tried to sell me on a higher priced repair. Everyone was very friendly and I was very happy! About 6 weeks later I noticed that the A/C was not as cold and wanted to get it back in for another recharge. I had an opportunity to speak to Bert for a few minutes and he was awesome! I even left there with a no charge for the recharge! This is an honest business and I would highly highly recommend!

Had a difficult electrical issue with my car, took it by auto specialists and they had it fixed the same day. Great mechanic shop.

I was in Lowes Hardware the other day when I ran into a guy with an Auto Specialties t-shirt. Not wanting to waste his time I asked the gentleman if he had a few minutes to spare. Within a few minutes of speaking with him I was convinced he had a wealth of knowledge about my truck. On Monday I decided to take off work and drove down to Huntersville to see if he could help me with my truck. Within a few hours he called me and said my truck was fixed. I'm not big on reviews but I feel my experience was so good I needed to tell more people about this hidden gem.
