NGK Laser Iridium High Ignitability Spark Plug SILZKBR8D8S (Box of 4) for Select 2010-2020 BMW

Fits select 2010-2020 BMW models, including 335i, 535i, M3, M4, X5, and X6 (SILZKBR8D8S).

NGK Laser Iridium High Ignitability spark plugs provide the ultimate combination of performance and longevity. Designed specifically for OE applications, these plugs feature an iridium-tipped center electrode paired with a platinum pad or fine wire tip on the ground electrode. This dual-precious metal construction provides a service life and durability profile significantly higher than standard platinum plugs, ensuring consistent ignition and even wear in high-stress distributorless ignition systems.

Each plug is built with a 98% pure copper core to aid in heat removal and prevent overheating, while the high-grade alumina silicate ceramic insulator provides superior strength and thermal conductivity. To ensure a long-lasting installation, the shells are treated with trivalent metal plating for maximum anti-corrosion and anti-seizing properties.
