NGK Spark Plug for BMW M3 and Z3 1996–2000

NGK spark plug 3641, design code PKR7A, covers the BMW M3 Base from 1996–1999 and selected Z3 applications from 1998–2000. The Z3 entries include the 1999 M Coupe and the Roadster years shown in the fitment table. A spark plug receives high voltage from the ignition system and fires it across the electrode gap to ignite the compressed air and fuel mixture. Electrode wear and deposits can contribute to a rough idle, hesitation, or misfires, making plug condition part of a complete ignition-system inspection. Match the NGK reference and the exact vehicle application when planning a replacement, and follow the vehicle's specified service interval and installation procedure.

Warranty: 24 Months / 24,000 Miles.
