Detailed Product Description

The NGK Laser Platinum Spark Plug 7415 features a platinum tip on the center electrode, which enhances wear resistance and maintains a stable spark over time. The copper core center electrode improves thermal conductivity, helping to dissipate heat efficiently and reduce the risk of pre-ignition. With two ground electrodes made from nickel, this spark plug ensures consistent spark exposure and reliable ignition. The standard ground electrode tip and configuration provide a balanced design suitable for the combustion chamber environment of BMW M3, Z3, and Z4 engines.

The spark plug’s pre-gap size of 0.036 inches is factory set to optimize ignition timing and combustion efficiency. Its flat seat design and 0.75 inch reach ensure proper fitment and sealing within the cylinder head. The 5/8 inch hex size allows for straightforward installation using common tools. Additionally, the non-removable nut electrical terminal type offers secure connection to the ignition wire. The heat range rating of 8 is calibrated to match the thermal requirements of the specified BMW models, preventing fouling and overheating.
