#1 Material of the Spark Plug
A crucial thing to consider while purchasing a spark plug is understanding which kind of plug you need. There are numerous types of metals that are employed to manufacture the required spark plug. Though the complete body of most spark plugs is identical, the electrodes are distinct.
The type of metal used to make the spark plug electrode is a major factor that governs the spark plug’s price and performance. The following are the electrodes available for spark plugs.
- Copper Electrode: These are the affordable and readily available in the market. The best part of using a copper electrode spark plug is that it goes well with almost all types of engines. However, it doesn’t offer much durability and hence wears off after 20,000 miles of use.
- Platinum Electrode: Platinum is a non-corrosive metal with respect to copper. Thus, it lasts way longer than an average copper electrode spark plug. As a result, Denso Spark plugs are one of the best platinum-based spark plugs available in the market.
- Double Platinum Electrode: These types of spark plugs are an upgrade to the platinum spark plug that offers better performance and durability.
- Iridium Electrode: NGK spark plugs are iridium-based spark plugs. Because of such a premium quality core material lasts longer than platinum spark plugs and offers a smooth drive up to 100,000 miles.
#2 Gap Between the Electrodes
Unfortunately, it is a misconception among people that prying the ground electrode away from the central electrode will make space for a good spark.
It’s completely false. Every engine has its own needs. Thus, there is no universal measurement for the gap of the spark plugs.
It is valid to some extent that prying the ground electrode away creates a good gap for the spark to happen. But, even then, the gap width varies from one model to the other. For example, some spark plugs may require a 0.55mm gap for efficient functioning, while others may need less.
The best way to check what is the desired value is to refer to the user manual. Once you know how much gap between your electrodes, you can easily pry or bend the ground electrode using a gap tool. There are different gap tools for spark plugs based on their core conductor.
Remember, never pry or bend the ground electrode too much since there’s a chance that you’ll scrape off the ground electrode and break the spark plug.
#3 Cost of the Spark Plug
From a commercial point of view, a buyer is likely to incline toward a product that benefits him at a minimalistic or reasonable cost. Usually, the price range for the spark plugs varies, starting from $2.5 to anywhere $15 at max.
The spark plug’s price directly relates to the conductor’s material, tech-inclusive design, making charges, durability, and efficiency.
A spark plug that costs $3 is supposedly the one that doesn’t offer much durability and wears out quickly. Such spark plugs are good to use in racing cars where they are changed at intervals.
The most common and affordable spark plugs fall in the range of $6 to $10, making up customer satisfaction. On the other hand, the pricey spark plugs $12-$15 is an iridium one that stays intact for an extended period and comes with many facilities.
#4 Heating Range
The heat range of the spark plug has a direct link to its efficiency. The ceramic coating on the spark plug provides insulation to the central electrode and protects the spark plug from thermal rupture. Moreover, the insulator dimensions have a significant role in controlling the heat flow in the spark plug.
For instance, if the ceramic insulation is less on the spark plug, more heat can regulate inside the chamber, and the tip can store more heat. It is how a hot spark plug works. On the other side, if the insulation on the spark plug is better than the previous case, then the plug will get cooler quickly. Hence, the chamber will conduct more heat away from the spark plug.
Demerits Of Choosing A Differently Insulated Spark Plug
There are both merits and demerits of a hot and cold spark plug. When a spark plug remains hot for a long time, the tip stores more heat leading to the mechanical damage of the spark plug. It is known as knocking.
Meanwhile, if a spark plug is colder than required, electric dirt can coat over the ceramic insulator, leading to energy loss. In this case, the spark plug would consume more voltage than stipulated.
#5 Shape of Electrode Tip
The shape of the tip of the electrode can also affect the performance of a spark plug. A pointed tip discharges more spark than a rounded tip spark plug. It is correlated with corona discharge.
In corona discharge, the sharp tip discharges more current or spark. It is because the area of the tip is minimized with the discharge strength as constant.
Hence, the effect is more in a sharp pointed tip in comparison to a rounded one. The new age spark plugs have a tapered tip for better efficiency. All of the spark plugs discussed above have pointed tips for maximum discharge.
Buying a spark plug has become a lot easier thanks to the bloom of the online market. Unlike the old days, where you had to go to the store to check the specs personally, today, you can do that with just one click and verify if it is the one for your Hyundai Elantra or not. To make things even easier, you can bookmark this guide for your future reference whenever you have to buy one.
