The NGK Iridium spark plug pairs a fine iridium center electrode with NGK's high-grade alumina ceramic and a 98% copper core for reliable starts and long life. Raised platinum or fine-wire ground tips promote even wear in distributorless systems. Trivalent plating and triple seals resist corrosion and leakage; recommended for vehicles originally equipped with OE DFE-type iridium plugs.
