YPC05 Iridium Spark Plug for BMW – OEM 97506 (SILZKBR8D8S / NGK 97506)
Premium iridium alloy center electrode ensures ultra-high durability and consistent performance under extreme temperatures. Laser-welded fine-wire tip minimizes voltage requirements for faster starts and smoother acceleration. Precision-engineered copper core dissipates heat efficiently, reducing pre-ignition risks in turbocharged engines. Exact OEM fitment (SILZKBR8D8S) for BMW N20, N55, B48, B58 engines – no ECU recalibration needed. Multi-ground electrode design extends service life to 60,000+ miles while maintaining fuel efficiency. Factory-sealed anti-corrosion plating prevents misfires in humid or salted-road conditions. Optimal for high-performance tuning, towing, or stop-and-go urban driving scenarios. Direct replacement for NGK 97506 with enhanced thermal conductivity for lower emissions. Vacuum-packed twin-tip iridium construction resists carbon buildup in direct-injection applications. Global bulk pricing available – identical specifications to dealership parts at 40% lower cost.
