This ignition system is an improvement over distributor ignition systems because it isn’t affected as much by rain or debris. The spark for the latter gets wasted because the air-fuel mixture was already burnt on the previous stroke. In a wasted spark ignition system, each ignition coil fires two spark plugs at once, one in the compression stroke’s cylinder and the other in the exhaust stroke’s cylinder. This is more efficient and longer-lasting which makes these plugs a great choice for a wasted spark ignition system, which exerts more wear on both electrodes than do other ignition systems. Prosĭouble platinum spark plugs have platinum coating both the center and ground electrodes. This is the recommended material for new cars with a coil-on-plug ignition system. These plugs also generate more heat, which reduces carbon buildup.
The platinum metal lasts longer than nickel alloy before being worn away. ProsĪ single platinum spark plug is similar to a copper/nickel spark plug, except that its center electrode has a platinum disc welded to the tip instead of only nickel alloy. That could adversely affect the performance of the vehicle. Many car manufacturers are now using iridium spark plugs in their vehicles, so it’s important to stick with iridium when replacing the plugs rather than downgrading to platinum or copper/nickel. These advantages are reflected in the higher price tag. These spark plugs have a small center electrode which requires less voltage to generate a spark. Iridium spark plugs last the longest since iridium is harder and more durable than platinum. Performs well under high-compression or turbocharged conditions.Appropriate for older vehicles built before 1980.

Check the owner’s manual for manufacturer recommendations. In some of these cases, installing more expensive spark plugs may be a waste of money. Some cars are designed to use copper spark plugs despite their shorter lifespan. Nickel alloy is a material that is soft and not very durable, so the spark plugs will need to be replaced more frequently than other types. It has the largest diameter of all the other spark plugs, so it needs more voltage to generate a spark. The center electrode of this type of spark plug is a copper core coated with a nickel alloy. Below you will find more details on each of these spark plugs and what they are good for.
The best spark plug varies depending on the vehicle. The main types of spark plugs are copper/nickel, iridium, single platinum, double platinum, and silver. However, some high-powered vehicles use two spark plugs per cylinder. In most gasoline-powered vehicles, the number of spark plugs is equal to the number of cylinders. Less voltage required makes for a more efficient ignition system. Newer spark plugs utilize smaller center electrodes in order to lower the amount of voltage required to generate a spark. The electrodes were traditionally made of copper but now they are also being manufactured from rare materials like iridium and platinum. When the voltage supplied from the ignition coil to the spark plug is high enough, the electrical energy jumps the gap, forming a spark. There is an insulated center electrode running the length of the spark plug and one or more ground electrodes on the bottom end, separated from the exposed end of the center electrode by a space known as a spark gap. The purpose of a spark plug is to ignite the compressed mixture of air and fuel in each cylinder of a gasoline-powered internal combustion engine.
