  • Spark plugs, especially those made from iridium, require less voltage to fire, thus lowering emissions and better combustion.
  • New ones reduce the amount of time need to start your vehicle, thus improving fuel efficiency. Old and worn-out ones case high fuel combustion, which requires a lot of voltage to start.
  • They help decrease the number of exhaust emissions. It is a result of the decrease in misfires due to old and written-off.
  • New ones maximize the engine’s combustion, thereby increasing acceleration and response in the event of an increase in speed.
  • A good, new and healthy plug also helps to ignite the engine to improve the combustion process, thereby allowing for a smooth ride.
  • Every time a car misfires, its ability to utilize fuel efficiently reduces by thirty percent. There’s a need to replace old ones with new ones that can help improve the fuel economy.
  • The item generally contributes to the overall health of your ATV. It helps reduce the risk of damage to the engine’s other components.

Types of Spark plugs

Spark plugs vary depending on the type of material used to make them. There are five types made from different materials, including copper, platinum, double-platinum, iridium, and double iridium materials.


Even though not commonly used today, copper plugs were the first to be used in machines. However, platinum plug type soon replaced it due to their efficiency and life span.


The new platinum spark plugs, unlike their predecessor, offer enhanced performance and improved fuel efficiency. They are also cheaper than iridium plugs, and you save on some cash since they last longer than the copper core plugs.


As the name suggests, the double-platinum core is the enhanced version of the single platinum plugs. As a result, their fuel efficiency is far enhanced than copper and single platinum plugs combined, and they last longer.


The type of material used to make iridium plugs have improved technology, improving mileage and efficiency, making them more reliable. Due to their diverse ability, they do not come cheap, but they will be worth every coin if you choose them for your ATV.


Double iridium spark plugs provide high engine performance than all the other four types combined. In addition, the two discs capsuled in the plug provide firepower for all types of weather, making it ideal for off-road cars.


What are the symptoms of a faulty spark plug?

Various symptoms indicate that the plug is faulty, and they include:

  • Lack of acceleration occurs when the accelerator loses its sensitivity and becomes unresponsive. It would be best if you changed them to enhance your ATV acceleration.
  • Machine misfiring is a symptom of a faulty product that causes high emissions and an uncomfortable jerky ride.
  • High fuel consumption by your ATV is another symptom that the product is faulty and needs to be replaced.
  • Other than the common symptoms of trouble starting your machine like a flat battery or low fuel, a faulty plug is the other reason why your car is not starting.
  • Engines surging occurs when it is not working as it should. It sucks more air than it needs is another symptom of a fault. It causes your vehicle to start and stop uncontrollably.
  • A rough idle that causes vibrations in the ATVs is yet another symptom. If not corrected, these symptoms could cause damage to the car.

Inquiries - Frequently Asked Questions

The following are the answers to your frequently asked questions on spark plug for ATV.

How can you determine whether your spark plugs are at their optimal temperature?

You can always see and tell if it is working at optimum temperature by checking the color of the insulator tip.

If it has a light gray tan, then it indicates that it is working at optimum temperature.

If you see the color change to dark blackish coloring, it indicates low combustion, an enormous gap, or a cold heat range. It shows that it is not operating at the right temperature.

You will know that it is overheating when you see a glossy appearance due to the melting of the insulating tip.

Wet deposits on the insulator tip are a sign of oil leakage. Low fuel quality and breached head gasket.

Yellowish-brown deposits on the insulator nose indicate a lead foul.

When it comes to spark plugs, how long do they last?

How long it lasts depends on the proper functioning of the engine. If it functions at its best, it will last 20,000-30,000. Averagely in a year, the mileage is 13,474 miles, and this enables the product to last for 1.5 to 2.5 years.

How often should I replace my spark plugs?

A high-quality product should serve for 30,00- 90,000 miles before being replaced. However, it would be best to consult with your deal on the specifics of your machine and which spark plug works best for it. Selecting the best for your ATVs will enable you to realize value for your cash while offering high performance.

Will the check engine light turned on by a faulty spark plug?

A faulty product will cause your check lights to turn on. It triggers the light to either illuminate or flash to indicate catastrophic misfires in the machine when it misfires. It would be best to change them to prevent damages like overheating and lead fouling.

What if your spark plugs are not replaced?

Like any other product, they also deteriorate with time, making them unable to generate the required spark to start the ATV. The incomplete air and fuel mixture leads to loss of power and eventually complete engine failure.

Is it better to use hot or cold spark plugs?

Please use a cold compared to a hot one. The cold spark plug will only cause the machine to foul, whereas the hot one will cause severe damages to your ATVs.

Is there a shelf life for unopened spark plugs?

There is no shelf life for an unopened product because they do not have fillers that expire after five years.

Final Verdict


Before buying a spark plug for your ATV, ensure you evaluate one compatible with your engine. Different plugs work best for different vehicles. Next, consider an efficient product that will enable you to realize value for your expenditure.
