    • 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

    • Worked great on 2016 BMW X5 5.0i M-Sport
Just to be on the safe side, I checked the gap on all 8 of the plugs I ordered. They were all spot on. Easy replacement on 2016 BMW X5 5.0i M-Sport. Amazingly easy job to do, considering it's a BMW. I took my time and had all 8 replaced within 1.5 hrs. Recommend.

    • Perfect replacements for BMW OEM spark plugs
My BMW X3 hit 100K miles and needed to change spark plugs. Saw these as "highly rated" on Amazon to replace my super expensive BMW plugs and gave it a try. They have worked perfectly if not better than the OEM plugs at a fraction of the price. One quick tip...some of the spark plug ports are hard to get to and you'll need a special flexible socket wrench to get the plugs in and out. You can also buy this on Amazon and can have the spark plugs replaced in no time. Good Luck! ... show more
