Buyer’s Guide

What are spark plugs?

Spark plugs are a type of electrical device that helps to create the spark needed to ignite the air/fuel mixture in an internal combustion engine. This ignition process is what powers your car. The spark plug has a metal electrode that is connected to the spark plug wire. This electrode is responsible for creating the spark that ignites the mixture.

What are spark plugs?

Spark plugs are made from different materials, but copper is the most popular choice. Copper spark plugs are known for their durability and ability to withstand high temperatures. They also have a lower resistance than other types of spark plugs, which means they can create a stronger spark [1].

How to install new spark plugs?

Installing new spark plugs is a pretty easy process that anyone can do with just a few tools. You’ll need a socket wrench, a ratchet, and an extension. First, you’ll want to locate the spark plug wire boot on the end of the spark plug. Gently pull this off being careful not to damage the boot or wire.

Next, use your socket wrench to loosen the spark plug (be sure to use the correct size socket). Once it’s loose, finish unscrewing it by hand and then carefully remove it from the engine. Take your new spark plug and screw it in by hand until it’s snug and then finish tightening it with your socket wrench. Be sure not to over-tighten as this can damage the spark plug. Finally, re-attach the spark plug wire boot and you’re all done!

If you’re having trouble getting the old spark plugs out or are unsure of which size socket to use, consult your car’s owner manual or a mechanic.
And that’s all there is to it! With just a few simple tools, you can easily change your spark plugs in no time [2].

General types of spark plugs

Copper spark plugs

Copper Spark Plugs are the most common type of spark plug. They are made from a copper core with a nickel alloy sleeve. The center electrode is usually made of nickel and iron. Copper Spark Plugs have a wide range of heat ranges and can be used in most applications.

The advantages of Copper Spark Plugs are that they are inexpensive and have a long life. Copper Spark Plugs also have good conductivity and can handle high temperatures. The disadvantages of Copper Spark Plugs are that they can wear out quickly, and the tips can break off.

Nickel alloy spark plugs

Nickel alloy spark plugs are made from a nickel-iron alloy. The center electrode is usually made of nickel and iron. Nickel alloy spark plugs have a wide range of heat ranges and can be used in most applications. The advantages of nickel alloy spark plugs are that they have a long life and good conductivity. However, you should avoid using them in high-performance engines because they can break under high loads.

Iridium spark plugs

Iridium spark plugs are made from an iridium-copper alloy. The center electrode is usually made of iridium. Iridium Spark Plugs have a very wide range of heat ranges and can be used in most applications such as high-performance engines. The iridium spark plugs are beneficial because they can handle high temperatures and have a long life. However, they are also very expensive and can be difficult to find.

Single platinum spark plugs

Single platinum spark plugs are made from a platinum-iridium alloy. The center electrode is usually made of platinum. These spark plugs are used in the engines of luxury cars. These spark plugs have a special construction that makes them last much longer – up to twice as long as copper spark plugs. Platinum is also a good conductor of electricity, so it can handle high temperatures. They have parts made of precious metals, so they are also more expensive than other types of spark plugs. Their operation is the same as that of other spark plugs.

Double platinum spark plugs

If you are looking for an even better quality spark plug, you can choose a double platinum spark plug. As the name suggests, these plugs have two Platinum tips instead of one. This makes them more effective and durable. The double-platinum spark plugs are suitable for all kinds of engines, including high-performance ones. However, keep in mind that they come with a higher price tag [3].

Key Features of the Copper Spark Plugs

Material features

Copper spark plugs are made of a soft metal that is good at dissipating heat. The threads on copper spark plugs are also treated so that they can resist corrosion from oil and other fluids. Copper is also a good conductor of electricity, which means that it can create a strong spark to ignite the air/fuel mixture in the combustion chamber.

Material features

Another advantage of Copper Spark Plugs is that they are less likely to “foul” or become coated with deposits than other types of spark plugs. This means that they will require less maintenance and will last longer. However, one downside of copper spark plugs is that they are not as durable as some other types of spark plugs and may need to be replaced more frequently [4].

Size and design

Copper Spark Plugs come in a variety of sizes and designs to fit most engines.

The most common size is 14mm, but there are also 12mm, 18mm, and other sizes available.
There are also different designs such as “taper seat” or “gasket seat” which refer to the way the spark plug sits in the engine.

Most Copper Spark Plugs have a “resistor” that helps to suppress electrical interference from radios or other electronic devices. This can be an important feature if you live in an area with a lot of electromagnetic interference. Finally, some copper spark plugs come with a platinum or iridium tip. These materials are more durable than copper and can help to extend the life of the spark plug.

Heat Range

The heat range of a spark plug is the measure of how much heat the spark plug can dissipate. The higher the number, the more heat it can dissipate. It is important to choose a spark plug with a heat range that is appropriate for your engine. If the spark plug is too hot, it can cause pre-ignition and engine damage. If the spark plug is too cold, it will not fire as often and will eventually “foul” or become coated with deposits. One way to determine the appropriate heat range for your engine is to consult your owner’s manual or talk to a qualified mechanic.

Gap Style

The gap style is the way the spark plug’s electrode is designed. The most common type is the “J” gap, which has a flat surface that allows for more complete combustion. The “V” gap is another popular design that uses two angled surfaces to create a smaller, more concentrated spark. Finally, there is the “U” gap which combines features of both the “J” and “V” gaps.

The “U” gap is becoming more popular as it is said to provide better performance and fuel economy.
The “J” gap is still the most common type of spark plug, however, so it is important to make sure that your engine can take advantage of the other gap styles before you switch.

How to maintain the Copper Spark Plugs?

Copper spark plugs are an essential part of keeping your car running properly. While they don’t need to be replaced as often as other parts of your car, it’s still important to keep them clean and in good working order. Here are a few tips on how to maintain your copper spark plugs:

  • Check your spark plugs regularly for any build-up of deposits or damage.
  • If you notice any deposits, use a wire brush or similar tool to remove them.
  • Make sure the gap between the electrode and the metal tip is correct – too wide and the spark won’t be able to jump, too narrow and it could cause misfires.
  • Replace your copper spark plugs every 20,000 miles or so to prevent any problems.

How to maintain the Copper Spark Plugs?

If you follow these tips, your copper spark plugs should last a long time and keep your car running smoothly [5].
