How To Choose The Best Spark Plugs For Your Vehicle

A spark plug is one of the most crucial parts of the car. It defines the horsepower and mileage to an extent. The design of the spark plug is very simple, but it can be tricky to buy it. You can’t just rely on the recommendation of the dealer for changing the spark plug. You need to know the factors that are going to impact your choice while buying the spark plugs. To help you in making the right buying decision, we have listed all the factors that you would need to consider while purchasing the spark plugs. Check out the details below.

  • Type of Spark Plug

The first choice that you would need to make is the type of spark plugs. There are four options available here. These options are copper spark plugs, platinum spark plugs, double platinum spark plugs, and the iridium spark plugs. If you want the best, then you can opt for the iridium spark plugs. They are slightly expensive, but they are very durable. In recent years, some of the manufacturers have started manufacturing silver-tipped spark plugs. These are expensive, and they have a short operating life, but they also have excellent thermal conductivity, which enhances the mileage and power delivery.

  • Gap Type

When we talk about the gap, we mean the electrode gap of the spark plugs. The gap is measured in millimeters, and you will find two types of spark plugs based on the gap between electrodes. These are the narrow gap and the wide gap spark plugs. The narrow gap spark plugs are better, but they need frequent maintenance. These type of spark plugs quickly gets dirty, and hence you will have to clean them frequently.

  • Material Used

You need to look at the material of the spark plug. Most of the speak plugs have a ceramic design,and this is the only best material for spark plugs. Ensure that the quality is up to the mark. Poorly designed spark plugs can wreak havoc on the engines. Do not buy the cheap Chinese products that can break inside the plug. Ensure that the material doesn’t corrode in the long term.

  • Size of Spark Plug

You also need to check the size of the spark plug. This factor translates to the compatibility of the spark plug with your vehicle. You need to map the specifications of the car with the spark plug compatibility list. Most of the spark plug manufacturers would provide you this information on the pack.

  • Price Range

Look at the price range of the spark plug. The platinum spark plugs are slightly expensive than the nickel or copper spark plugs, and the iridium spark plugs are the most expensive ones. You can buy the spark plugs as per your budget. Remember that spending a little extra on the spark plugs will be beneficial for your car, and you will feel the difference when you will floor the pedal of your vehicle.

  • Pack Size

You would need to purchase the spark plugs as per the number that you need. Most of the car needs 4 spark plugs, but some large SUVs require 6 or even 8 spark plugs. Buy the pack size as per the requirement of your vehicle and ensure that you change all the spark plugs when anyone needs replacement. It is not a wise decision to replace only a single or a pair of spark plugs.

  • Heat Rating

You would also need to check the heat rating of the spark plugs. You have an option between low heat rating and high heat ratings. The spark plugs that have a low heat rating are good enough for light vehicles, but if you have a large SUV or if you have a performance vehicle, then you would need a high heat rating spark plug. Ensure that you check the heat rating of the spark plug before you buy one.

  • Warranty & Brand

You can also check the warranty applicable to the spark plugs. Considering the warranty will save you from the manufacturing defect in the future. If you buy the spark plugs from a reliable brand, you can be sure of the quality of the spark plugs. We have mentioned this earlier, but we would like to mention the point again. Do not buy the cheap quality spark plugs.

Always ensure that you are buying the best possible option within your budget.
