PRODUCT DESCRIPTION

Often specified as original equipment, NGK Laser Iridium spark plugs are the best combination of performance and longevity. Iridium tip is six (6) times harder than platinum providing the strongest ignitability and the longest life possible. Most Laser Iridium spark plugs feature a platinum pad on the ground electrode for even wear in DIS ignition systems. OE engineered for specific vehicle applications.
