Gasket sealing process eliminates the possibility of combustion gas leakage over a much wider heat range than ordinary plugs. The patent-pending triple gasket sealing process prevents carbon build-up and pre-ignition of fuel in diesel engines. It also reduces emissions by up to 95%. Iridium Premium is made from high-purity aluminium, which has a low coefficient of thermal conductivity. It can be used with any type of fuel. Notably, it is more expensive than regular petrol.

Value for Money

G-Power Platinum. The platinum plug is designed to operate over a much wider heat range than ordinary gaskets. It has been tested and found to be non-polluting, which means it does not pose any risk of carbon buildup or pre-ignition. Notably, the process was first used in the 1960s. The plug’s sealing process was developed by German company G-Power in 2015. The plug is made from recycled materials. The system uses only one part per cylinder.

Most Discussed
