Editor's Pick

Champion copper plus spark plug has a copper core center electrode that provides increased conductivity and heat control while providing good overall wear characteristics. The plug is built to ISO and SAE standards for proven performance. It features an anti-seize coating, which prevents the formation of metal oxide during installation. The plug’s weight is less than 0.3 kg per pound. Notably, it was first introduced in 1984.

Best Budget

G-Power Iridium Platinum Alloy Spark Plugs offer superior performance and reduced emissions. The insulator’s triple gasket seal reduces the risk of combustion gas leakage, which is good for both diesel engines and petrol engines. The plugs are available in three sizes: Standard, Premium and High Performance. It has been tested to ensure that it does not cause any damage to the engine or fuel supply. Notably, this comes with a price tag of?1 lakh.

Most Discussed

Platinum-iridium and fine-wire double platinum plugs feature platinum pads on both electrodes. The platinum pad is used to prevent corrosion of the platinum wire, which can lead to rusting. It also helps in reducing friction between metals like nickel and copper. This allows for longer service intervals without damaging the electrical conductivity. Notably, platinum has been banned in all vehicles since it was discovered to be harmful to the environment.
