So i hope you agree with me when i say:
“Continuing to drive with worn out or damaged
spark plugs can cause engine damage”
Your car’s engine cannot start without a spark plug. So it is very important to keep good care of your spark plug. However spark plugs tend to deteriorate by time and not changing a bad spark plug can cause engine damage. The only way to prolong this issue and to get benefits of changing spark plugs is to always use the best spark plugs you can find for your car from the get-go.
Fortunately, we have done the research to provide you with not only original, but the best spark plugs for horsepower you can find in the market at a reasonable cost.
We have also included some information about “Platinum vs Iridium Spark Plugs” So you can find the best spark plugs for horsepower according to your demands.

The list above was made after the combined effort of the consumers and our research team. The list contains the best Spark Plugs for horsepower of a car. Much care is usually not needed regarding spark plugs but it would still be advised since a bad plug can potentially cause harm to the engine and as the saying goes:
“A well kept vehicle provides a far better experience than a poorly kept one.”
Platinum vs Iridium Spark Plugs
Sparks like to jump around to the sharpest point from the center electrode to the sharpest point of the side electrode. So these points ought to be durable to withstand constant sparking. Therefore materials like Copper, Platinum and Iridium are used to create these points.
Platinum Spark Plugs
A Platinum Spark Plug consists of platinum electrode tips (as the name suggests). The benefit of using platinum spark plugs is that due to the high melting point of platinum, it can outlast many copper and other kinds of spark plugs by a gap. But that also means it has lesser conductivity than these metals. On the plus side this leads to more stable current flow but the raw performance suffers quite a lot.
Iridium Spark Plugs
Iridium Spark Plugs are the best when it comes to handling heat. Not only do they have higher melting points than platinum and last longer but they also do not suffer from that backlash as platinum. With great conductivity, an iridium spark plug is your go-to if you want the best spark plug. But due to iridium being very expensive, the price of iridium spark plugs is naturally higher than platinum or copper.
