Steven Estevez, Chief Editor

A spark plug is a tiny device that plays a huge role – in fact, it’s a critical component of the engine combustion system. A vehicle cannot function properly or simply go anywhere if the plug is faulty or broken. One small but mighty detail can improve the work of the ignition system and increase your vehicle performance drastically or cause serious harm to the engine. That’s why it’s so important to use the proper spark plug, compatible with your engine capacity and vehicle model.

Spark plugs are the most important parts in your engine. They ignite a mixture of fuel and air in the cylinders resulting in internal combustion. Consequently, this process pumps the pistons creating movement in your vehicle. Over time, even the best spark plugs for performance can get worn out resulting in misfires. Thankfully, they can be replaced. How does a driver select the best rated spark plugs or figure out what type of spark plug is best for their car? We’ve reviewed the best spark plug brands available today along with some insightful details that can be used to tell the difference between good and bad spark plugs when buying spark plugs.

IRIDIUM SPARK PLUGS BENEFITS

Performance Spark Plugs Fuel And Air Ignition

Spark plugs are responsible for activating the operation of pistons in your cylinders. They are equipped with two leads that are not in contact but are so close that electricity can cross the distance between. Upon activation, the best racing spark plugs create an electrical arc between these leads that ignites the mixture of fuel and air in the cylinder. The resultant explosion pushes the piston back and turns the crankshaft leading to vehicular motion. The process running in this best performance spark plug is known as internal combustion. The spark plugs, timer and electrical wires create your vehicle’s ignition system. Drivers that are wondering what’s the best spark plug for performance should select those with an Iridium center electrode.

Best Spark Plug Engine Cooling

Spark plugs cool down the engine by transferring heat away from the cylinders. Normally, the best spark plugs on the market are encased in ceramic material. This insulator directs heat away from the cylinders after the internal combustion explosion occurs. Collectively, the spark plugs in your engine direct this heat to the car’s cooling system. In doing so, they preserve the proper functionality of your engine.

WHAT ARE THE BEST SPARKPLUGS KEY FEATURES

Top Rated Spark Plugs Electrode Material

The material that is used to manufacture the electrode of the best sparkplugs is a very important feature. This material can be copper, platinum or iridium. Each electrode material has its advantages and disadvantages. Modern automobiles use platinum or iridium electrodes because these materials are highly resistant to heat, have high conductivity, require lower levels of voltage to operate and last for many years without requiring replacement.

What Are The Best Spark Plugs Insulator Material

Spark plugs not only ignite the mixture of fuel and air in the cylinder, they also conduct heat away from the engine through their insulators. Spark plugs use ceramic insulators. One variety of these is the smooth ceramic insulator which extends the plug into the cylinder head using an evenly textured tube. Another variety is the ribbed ceramic insulator which has a series of ridges around the circumference of the plug. This type is commonly used in the best brand spark plugs because it reduces the chances of flashover.

Recommended Spark Plugs Voltage Capacity

Spark plugs require a substantial amount of electrical voltage to function. Standard spark plugs require electrical levels of between 12,000 and 25,000 volts to fire properly within the cylinders. High performance vehicles are usually fitted with the best high performance spark plugs that operate with electrical voltage levels of 45,000 volts. This type provides a longer, hotter spark for maximum explosiveness and optimum power production.

FAQ – ALL YOU NEED TO KNOW ABOUT THE BEST SPARKPLUG

FAQ

Q: Why are spark plugs so important? 

The engine cannot function properly without spark plugs – this small detail creates the spark to ignite the air-fuel mixture in the combustion chamber; roughly said, this ignition starts your vehicle. 

Proper spark plugs help to achieve better engine performance, while faulty ones decrease fuel economy and affect engine work. Spark plugs have to be maintained and changed regularly, otherwise sooner or later your engine will suffer damages due to misfires and detonations. 

Q: What are the symptoms of a faulty spark plug? 

  • Common symptoms of a broken or faulty plug include: 
    • Trouble with starting the vehicle, hard car starts. 
    • Poor fuel economy. 
    • Rough idle. 
    • Misfirings.
    • Slower acceleration. 
    • Engine hesitating or surging. 

If you experience one or more of these issues, it’s time to change your spark plugs. 

symptoms-of-bad-spark-plugs

Q: When should I change spark plugs? 

It depends on the type of plug you use. Copper plugs have a recommended replacement interval of 20 000 miles. Platinum plugs need to be changed every 50 000 miles.  Iridium plugs last the longest and can achieve 80 000 – 100 000 miles of usage before the replacement. 

Spark plugs require routine maintenance and service. Operating under extremely high temperatures, spark plugs are prone to damage and wear, so you have to replace them regularly to maintain proper engine functioning.  

Q: How to choose proper spark plugs for my vehicle? 

To find the right spark plug for your car you have to consider the following criteria: 

  • Physical dimensions and characteristics (size, material, etc.). 
  • Heat range. 

Always check if the spark plugs you’re going to buy are compatible with your vehicle brand. 

Important: never choose spark plugs by their visual appearance. Even if two plugs look absolutely identical and have the same length, diameter, thread pitch, etc., they can still be very different when it comes to their heat range. 

Q: What is heat range and why is it so important? 

Heat range determines how hot the spark plug gets during engine operation. If you get a spark plug with lower than recommended heat range, it will lead to deposits buildup, and, as a result, fouling will occur.  If you get a spark plug with higher than recommended heat range, it will lead to preignition and sometimes even detonation and engine damage. That’s why it’s so important to buy the spark plugs with the heat range that matches the engine requirements – a proper plug will get hot enough to burn off the deposits and prevent fouling, but not too hot, to avoid preignition. 

Q: What is the best spark plug? 

There are many tried and trusted brands that produce high-quality durable sparks, but the best spark plug is the one that is compatible with your vehicle brand and engine capacity.   

Q: Should I always buy the same brand of the spark plugs? 

It is recommended to stick to the brand of the spark plugs that originally came in your engine. However, if you want to upgrade your spark plugs, for example, get platinum plugs instead of copper ones, you’re free to choose between many different brands available on the market. Just make sure that you use the same type of spark plugs.  

Q: What is the difference between copper, platinum, and iridium spark plugs?

  • Copper spark plugs are the cheapest and shortest-lasting ones – it’s a nice option for the vehicle owners who are tight on money.
  • Platinum plugs – mid-level option, durable, almost as good as iridium ones. Have a stronger spark than copper plugs. 
  • Double platinum – have platinum discs on center and ground electrodes. Offer enhanced performance and durability. Important: do not use double platinum spark plugs unless it is recommended by your vehicle manufacturer. 
  • Iridium spark plugs are the most innovative, durable and long-lasting ones, they are a bit pricey, but still worth the money. Iridium is considered to be the best material for spark plugs that offers the strongest spark. 

Iridium and platinum are precious metals – they are hard and therefore have higher melting temperatures compared to the electrodes in copper spark plugs. 

Q: How many spark plugs do I need for my Chevy Silverado 4.8? 

It depends on the number of cylinders your engine has. Vortec 4.8 is a V8 engine – it means your engine has 8 cylinders. You’ll need 1 spark plug for 1 cylinder, so the total amount would be 8.

Q: Can I change Vortec Spark Plugs by myself?

If you have all required tools (torque wrench, ratchet set, spark plug wire puller, gap gauge, special pliers, etc.) and, what’s even more important, your engine has easy access to its rear bank, then you can try to change the spark plugs by yourself. If you don’t have tools and some experience – better ask an automotive technician for help. 

Q: What if I install the wrong plugs for my Vortec 4.8? 

One of the most mistaken beliefs is that all spark plugs are more or less similar and interchangeable, so you can buy any plug you want and use it. But in fact, this tiny can cause significant harm to your engine because of its improper heat range. If your new plug is hotter than the original one, most probably it’ll cause electrode erosion and misfiring, preignition, or even detonation. If your new plug is colder than the original one, it will lead to misfiring and rapid fouling. 

Q: Spark plugs manufacturer says I have to gap the plugs, how can I do that? 

Each spark plug has a gap between the center and side electrodes. You have to adjust the distance (gap) between the electrodes so that your plugs fire efficiently. You’ll have to use a special tool called feeler gauge – it will help you to measure the gap widths. 

First of all, you have to check your owner’s manual and find the recommended gauge (the distance between electrodes). Select the correct number on your feeler gauge. Using this tool, bend the electrodes and adjust the distance between them. Make sure that the gap between them is not too wide or narrow – to do that, run the gauge through the gap. 

If you cannot or do not want to gap the plugs, you can buy already pre-gapped ones.
