  • High-Quality OEM Spark Plugs — Reliable Performance and Long Life from NGK
The NGK 97506 Laser Iridium spark plugs come as a 4-pack and are a solid choice for both performance and longevity. These are often specified as OEM parts, and the quality shows — the construction is precise, the metal threads are cleanly cut, and the iridium tips are well-centered for consistent ignition. Installation is straightforward, and once installed, the engine runs noticeably smoother with quicker starts and steady idle. The iridium design helps deliver strong, efficient sparks while resisting wear far better than standard copper or platinum plugs. They’re ideal for drivers who want OEM reliability with minimal maintenance over time. As with any spark plug, be sure to verify fitment for your specific engine before ordering, since NGK offers different models across vehicle types. Overall, these Laser Iridium plugs offer excellent durability, performance, and peace of mind — a dependable upgrade or replacement for any compatible car or truck. ... show more

  • NGK has a superior edge
What can I say? They’re spark plugs. Like having these in my BMW a lot more than Bosch. Built for high performance, cold start is zippy, better throttle response.
