NGK 7415 Spark Plug

NGK Laser Platinum Spark Plug 7415 Overview

NGK Laser Platinum Spark Plug 7415 is a direct-fit ignition component built for BMW applications that call for a 12 mm, flat-seat plug with a 0.75 reach and 5/8 hex. It uses a platinum center electrode, nickel ground electrode material, and a 5,000 ohm resistor to support stable ignition performance in the BMW M3, Z3, and Z4 applications listed below.

The Laser Platinum line focuses on OE-style construction and durability, with NGK’s long history as an original equipment supplier reflected in the plug’s materials and design. Part number 7415 is also identified as DCPR8EKP, making it easier to confirm the correct replacement during service.
