Spark Plug Buying Guide: Everything You Need to Know
Spark plugs are an essential part of your engine's ignition system. They ignite the fuel mixture within the engine, providing power to the vehicle. However, with so many options available in the market, selecting the right spark plug for your vehicle can be a daunting task. In this article, we will guide you through everything you need to know before buying a spark plug.
Types of Spark Plugs
There are two main types of spark plugs: copper and iridium. Each has its advantages and disadvantages, so it is essential to understand their differences before making a purchase.
Copper Spark Plugs
Copper spark plugs have been around for many years and are a popular option for their affordability. They have a solid copper core, which helps transfer heat away from the tip of the electrode quickly.
One of the significant advantages of copper spark plugs is that they have a high thermal conductivity, which means they can dissipate heat quickly. As a result, they can handle high temperatures and can last up to 20,000 miles.
However, copper spark plugs have one significant disadvantage: they wear out quickly. They are prone to corrosion and can become dirty. As a result, they require frequent replacements.
Iridium Spark Plugs
Iridium spark plugs are relatively new in the market but gaining popularity quickly. They consist of a small iridium tip at the center of the electrode, which helps improve the spark and the longevity of the plug.
One of the significant advantages of iridium spark plugs is that they have a long lifespan – up to 100,000 miles – which means they require less frequent replacements. They also provide a more consistent spark and better fuel economy.
However, iridium spark plugs are relatively expensive compared to copper spark plugs. It is also essential to note that not all engines are compatible with iridium spark plugs. Therefore, it is crucial to check the vehicle's owner's manual to determine if iridium spark plugs are recommended for your car.
Heat Range
The heat range of a spark plug refers to its ability to dissipate heat. It is essential to select the correct heat range for your engine. An insufficient heat range can cause the spark plug to overheat, leading to pre-ignition, engine knock, and damage to the engine. On the other hand, a plug with a heat range that is too high can cause the fuel mixture to burn too slowly, leading to fouling or buildup on the spark plug.
The heat range is primarily determined by the length of the insulator nose. A shorter insulator nose means the heat range is hotter, while a longer insulator nose means the heat range is colder. Spark plug manufacturers offer different heat ranges for different engines, and it is crucial to consult the vehicle's owner's manual to determine the correct heat range for your engine.
Gap Size
The gap size refers to the distance between the center and ground electrode. It is essential to select the correct gap size for your engine. An incorrect gap size can cause a weak spark or a misfire, leading to reduced performance, engine damage, or excessive fuel consumption.
The gap size is mainly determined by the engine's ignition system, and it is crucial to consult the vehicle's owner's manual to determine the correct gap size for your engine.
Resistor vs. Non-Resistor
Resistor spark plugs have a built-in resistor that helps reduce radio frequency interference (RFI) – or electromagnetic interference (EMI) – that can cause malfunction or damage to the vehicle's electronic components. Non-resistor spark plugs, on the other hand, do not have a resistor and can generate a high level of RFI, which can cause electrical noise or disturbance.
Most modern vehicles come equipped with a resistor or platinum-tipped spark plugs to reduce RFI. It is essential to consult the vehicle's owner's manual to determine the correct type of spark plug for your engine.
Brand
When it comes to spark plugs, there are many brands available in the market, each with its unique features and advantages. It is essential to select a reputable brand that offers high-quality spark plugs and a warranty.
Some of the top spark plug brands in the market include NGK, Bosch, Denso, Champion, and AC Delco. Each of these brands offers a range of spark plugs that are suitable for different engine types and applications. It is crucial to research the different brands and read reviews before purchasing a spark plug.
Conclusion
Selecting the right spark plug is crucial to ensure optimum engine performance, fuel efficiency, and longevity. Copper and iridium spark plugs are the two main types of spark plugs available in the market, each with its advantages and disadvantages. It is also essential to select the correct heat range, gap size, and type (resistor vs. non-resistor) of spark plug for your engine. Lastly, it is crucial to select a reputable brand that offers high-quality spark plugs and a warranty.
