Spark Plugs

Think of a spark plug as a tiny bolt of lightning. The spark of electricity emitted by the spark plug creates ignition for the internal combustion needed to start your car. By putting the engine's pistons in motion your car can power up and stay powered up. Located in the engine of your car,  spark plugs are built to withstand extreme heat and pressure within your cylinders. Without this spark your car won't start or go anywhere. Spark plug health is directly related to your engine's performance; therefore, you want to make sure your spark plugs are not bad or weak. Without healthy spark plugs your car can't sustain maximum power and you could see a drop in gas mileage. So how can you know when it's time to install new spark plugs?

Here are a few signs that your spark plugs are going bad:

  • Poor fuel economy (lower gas mileage)
  • Slow acceleration
  • Difficulty starting your vehicle
  • Engine misfiring (when an engine misfires it causes the vehicle to halt for a second before continuing it's usual movement)
  • Rough Idling
  • Engine surging (engine surging is when your vehicle sucks in more air than usual in the combustion process, causing the vehicle to jerk and then slow down or continually start and stop)

Most auto manufacturers recommend having new spark plugs installed every 30,000 miles; however, spark plug longevity depends on the condition and type of spark plug. Copper plugs have the shortest life, while spark plugs made of more advanced and durable materials can last up to four times longer than a copper spark plug. If you've noticed any of these symptoms we suggest having your car inspected in order to prevent any further problems.
