An Overview On Spark Plugs

All machines that use gasoline engines are outfitted with spark plugs. This includes automobiles, lawnmowers, watercraft and aircraft. Spark plugs are responsible for creating the electricity needed to ignite the fuel mixture to start the combustion process and turn on the engine. Depending on the type of machine, you will most likely be able to replace the spark plugs on your own, without having to schedule an appointment with a mechanic.

As you begin shopping for the best spark plug, you’ll want to first make sure the plug meets International Organization for Standardization (ISO) and Society of Automobile Engineers (SAE) standards. You don’t want to invest money in a spark plug that won’t deliver reliability and durability.

Look for a spark plug that is able to improve your gas mileage and provide a faster start. For example, the NGK G-Power Spark Plug, 4-Pack uses a G-power platinum alloy that enhances its performance. The ground and center electrodes are able to retain a precise gap, while also creating a greater spark.

Review the spark plug’s outer shell next. You’ll find the Champion RC12YC Spark Plug uses a special TinTac and ULTRASEAL shell to protect the spark plug from corrosion. Corrosion is a spark plug’s enemy and will lead to the plug needing to be replaced prematurely.

Examine the design of the spark plug’s tip next. For example, the DENSO PLATINUM T T Spark Plugs, 6-Pack has a specially designed twin-tip that increases its ability to ignite. Others are made from a .6 millimeter laser-welded fine platinum that reduces the voltage required to start the engine.

Consider a spark plug that is designed to handle intense conditions if you’re into power sports. The E3 Spark Plugs Power Sports E3 Spark Plug is a great choice for this, as it’s made using an yttrium-enhanced alloy to that reduces side wire temperature by 8%. It’s also made with colder heat ranges, so you can make modifications to increase performance.

DWYM Fun Fact

In 1770, a man by the name of Alessandro Volta was able to ignite a toy gun with a spark from a leyden jar. This concept was improved upon and by 1860 a spark plug was created and listed in a patent filed by engineer Jean Lenoir. However, there was still a lot of work that had to be completed to make the spark plug more reliable.

Spark plugs were able to be marketed to the public by 1909, after Robert and Frank Stranahan made the spark plug more effective with a longer life span. Today, there are literally hundreds of different spark plugs for everything from vehicles to boats to aircraft.

All you need to do is select your car’s year, make and model from the drop-down boxes and click the “check fit” button.
  • YouTube is flooded with step-by-step videos that will visually guide you through changing your machine’s spark plugs, whether that’s your lawnmower or family automobile.
  • If you have a 4-cylinder vehicle, you’ll need four spark plugs. Vehicles that have 6-cylinders require six spark plugs. It’s important to know how many spark plugs your automobile needs before place an order, otherwise, you may end up ready to do the job without the right number of plugs.
