Our daily lives are enriched by cars. Thanks to their invention, we can travel anywhere and everywhere. It is important that your vehicle is in top shape and all parts are working properly.

This prevents delays and accidents. Cars have become more than just a mode of transport. Parts and vehicles are designed to last.

Best Spark Plug

The most important thing when it comes to parts is the choice of the right spark plug. This article will help you find the best spark plugs to fit your vehicle. Let’s get started.

Different types of spark plugs

Know that there are currently four types of spark plugs on the market. These are the most popular:

  • Copper core spark plugs
  • Spark plugs made of Iridium
  • Platinum spark plugs
  • Double platinum spark plugs
  • Copper Core Spark plugs

They are the most affordable type of vehicle you can purchase. They can travel between 20,000 and 40,000 miles per use and are available for purchase from $1-3. These are the longest conductors, and they work well for those who don’t travel as much.

Iridium Spark Plugs

They are less conductive than Copper Core, but can still work well at low temperatures. These can last for up to 60,000 miles, and while they aren’t as efficient as copper, they can be counted on to have a longer lifespan than copper.

Platinum Spark Plugs

They can also work at low temperatures, like iridium, but are more susceptible to overheating. They can be more durable than copper and iridium.

Double Platinum Spark Plugs

These are the upgraded versions of platinum sparkplugs. They can last longer and improve engine performance. They aren’t the best conductors, but they have the longest lifespans of any engine.

Denso (4504) PK20TT Platinum TT Spark PlugDenso (4504) PK20TT Platinum TT Spark Plug

Denso is another great manufacturer of spark plugs. This spark plug is made using twin-tip technology and has an 11mm platinum central electrode. This unit also includes a 11mm titanium ground electrode, which is stronger than other versions.

This plug improves fuel economy, so you will not be burning as much fuel when it is attached to your vehicle. The Denso PK20TT is faster than other plugs.

The plug is also equipped with an alumina powder insulation. This insulator is purified to provide both dielectric strength and thermal conductivity. This feature allows the plug to withstand wear and tear under extreme stress.


  • It is faster than other plugs.
  • It can save you fuel.
  • It is dielectric.
  • It can withstand all stress.


  • It doesn’t work with all cars.
  • Could cause misfires
  • It may not work with bikes.

Denso is our next plug. The SK20R11 iridium sparkplug is made to last a very long time. It’s 6x more durable than other Denso plugs, and 8x stronger than platinum plugs on the market.

It has the strength and durability of iridium, so electrode wear is virtually non-existent. The spark plugs are resistant to extreme racing and driving conditions thanks to the platinum-ground electrodes.


  • It is extremely fast and efficient.
  • Even when it is idle, it stabilizes combustion.
  • It is made to last.
  • It is extremely reliable.
  • It has a high melting temperature.
  • It is available at an affordable price.


  • It is inexpensive and works exactly like other plugs.
  • It is not compatible with all cars.

Bosch (4501) FGR8DQI Platinum IR Fusion Spark PlugBosch (4501) FGR8DQI Platinum IR Fusion Spark Plug

This plug features a fused platinum-iridium center electrode. It is then sintered into an extended insulator nose. This creates a temperature that self-cleans after a few seconds of the vehicle being started.

It’s also resistant to wear and tear, so it will last for a long time. Bosch’s unique surface air gap technology makes this plug stand out. It has four ground electrodes which are specifically designed to produce the powerful spark.

It achieves maximum horsepower without increasing or decreasing the voltage. The spark plug is protected by four yttrium-ground electrodes, which are designed to resist oxidation and wear. Your plug will last longer thanks to this.


  • It’s easy to set up and doesn’t require any adjustments.
  • The fusion voltage is less stable over time than other iridium-plugs.
  • It is more reliable and has a longer lifespan.
  • It works very well.


  • Other vehicles may not be compatible.
  • Customers complained that their plugs quit working after 5000 miles.

These spark plugs work well with most cars we have today. These spark plugs are made using the most recent technology and can be used as an alternative to your original parts.

This plug’s iridium content has the highest melting point and strongest of all metals. This makes it durable and wear-resistant. They perform better than spark plugs made of platinum or conventional materials.


  • It delivers smooth and stable performance.
  • It provides quicker acceleration.
  • It makes cold engines more efficient.
  • It reduces the need for fuel.
  • It prevents the spread of combustion gases.


  • Customers complained of receiving defective plugs or reject plugs.
  • Not all vehicles may work.

Autolite APP104 Double Platinum Spark PlugAutolite APP104 Double Platinum Spark Plug

This plug is a favorite. These spark plugs are made of platinum tips and platinum on the sides and center electrodes. They can reduce gap wear, which can prolong the plug’s life.

It maximizes the vehicle’s engine performance and improves fuel economy. The electrodes’ center fires quickly and is more efficient than other types. The electrodes also have a lower voltage, making it easier to start your car.

This plug’s platinum alloy is designed to last longer. The plug also features a nickel-plated steel shell that is resistant to corrosion.


  • This plug can jump start your engine much faster than other types.
  • It is available at a fair price.
  • It can do amazing things.
  • It is durable.
  • It does the job.


  • Customers complained that the porcelain portion of the plug was weak, while others complained about the gap.
  • If you experience such problems, make sure to immediately contact the company.
