BMW Spark Plug (Iridium IX) – NGK Iridium IX 6546

NGK Iridium IX are designed specifically for the performance enthusiast. Each plug offers extreme ignitability, improved throttle response and superior anti fouling characteristics. Fine Iridium tip ensures high durability and a consistently stable spark. The Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines. Plug benefit include: outstanding acceleration, high fuel efficiency and durability. The spark plug is a critical component to the proper running engine. In a conventional gasoline engine, the air fuel mixture is ignited by the spark plug to drive the piston down and convert this energy to horsepower. If your spark plugs aren’t in good shape, this crucial process can be severely hindered to the point of power loss, hesitation, misfires, and poor start up performance. Typical service schedule for standard copper tip spark plugs is between 10,000 and 30,000 miles. Iridium plugs have a more durable (but weaker) electrode that can last upwards of 60,000 miles, and platinum plugs can be rated to go as far as 100,000 miles before the electrode is spent. When replacing spark plugs, be sure to abide by the part numbers in your owner’s manual for best performance, and always use dielectric grease to make a sealed and secure electrical connection.
