NGK Laser Iridium Spark Plug Box of 4 (DILKAR7C9H)

This is a box of four NGK Laser Iridium spark plugs, part number 91215. These are designed as direct replacements for your vehicle's original equipment, offering a great balance of performance and how long they last. The iridium-tipped center electrode is significantly harder than platinum, giving you a durable spark plug that holds up well over time. Plus, the pure alumina ceramic insulator helps manage heat effectively, and the copper core aids in removing excess heat from the plug itself, ensuring reliable starts.

You'll find these plugs feature a raised platinum pad or fine wire tip on the ground electrode. This design helps them wear evenly, especially in modern distributorless ignition systems, and contributes to a more consistent spark. The trivalent metal plating on the exterior helps prevent corrosion and seizing, making them easier to remove down the road. NGK uses triple seals to prevent any leaks, ensuring everything stays contained as it should.
