NGK Laser Iridium spark plug set (box of 4) combines fine-wire iridium technology with OE-level quality for durable ignition. The iridium center electrode resists wear substantially more than platinum, while NGK’s pure alumina ceramic insulator and 98% copper core help manage heat and provide dependable starts. Recommended for vehicles with OE SPE iridium plugs, these units include corrosion-resistant plating and triple seals to prevent leakage.
