NGK Laser Iridium Spark Plugs feature a laser welded iridium center electrode tip which ensures high durability and a greater spark while the platinum disc welded to the backside of the ground electrode provides a longer life.
Always used NGK plugs, a lot of the main car manufacturers use them, although they label them as their own and double the price (they leave the stamp on the metal body). Never had any problems.
