There are two prominent types of spark plugs created by manufacturers. These are the performance type and standard spark plugs.
Performance spark plugs have a better combustion efficiency, while standard spark plugs have better durability and longevity.
If you want to get more detailed, spark plugs can be made with different kinds of metals. Each of these metals affects the kind of performance that the spark plug can achieve.
Copper spark plugs are the most typical and standard metal used in spark plugs. This is because copper conducts electricity very well.
This spark plug is usually one of the cheaper types on the market.
Another metal that is used to make spark plugs is Platinum. This metal is more durable than copper because it prevents rapid electrode wear.
This is also a much more expensive spark plug than the Copper one.
Iridium spark plugs are the most beneficial for vehicles. These spark plugs have the best performance and can improve the firing efficiency by a lot.
It is also not as expensive as platinum spark plugs but more durable than the Copper spark plugs.
Spark Plug Sizes
There are three available spark plug sizes; 0.81, 0.75, and 0.68 inches. The gaps in these sizes range from 0.035 to 0.070 inches.
