Product Description

The NGK 94201 Laser Iridium Spark Plug (service code SILZKGR8B8S) is engineered to deliver reliable ignition performance, long life, and stable combustion in modern high-efficiency engines. Its laser-welded iridium center electrode offers superior ignitability and durability compared with conventional plugs, while the platinum ground pad helps ensure even wear and consistent spark quality. The high-grade ceramic insulator, copper core, and built-in resistor provide excellent heat transfer, noise suppression, and durability across varied driving conditions.

Specifically confirmed for use in a range of **BMW 2-Series, 3-Series, and M-Performance models** with B46, B48, and B58 engines, as well as select **Mini Cooper S** variants, the NGK 94201 spark plug meets or exceeds OEM quality and performance standards. It's ideal for maintenance or replacement during routine service intervals to help maintain smooth operation, responsive throttle, and consistent combustion. Always refer to the official vehicle service manual for proper torque and gap settings when installing.
