NGK 3199 Spark Plug For US E36 M3 S52 (BKR6EQUP)

Direct fit for all BMW US S52 engines. 

Multi-ground electrodes improve ignition capabilities and are less sensitive to increased voltage requirements due to gap growth. Designed to specific manufacturer ignition requirements, NGK's multi-ground plugs maintain all the features of their standard plugs, including:

• Corrugated Ribs to Prevent Flashover
• Pure alumina silicate ceramic insulator, providing superior strength and better heat transfer
• Copper core to aid in heat removal
• Triple seals to prevent leakage

Available as a single plug or set of 6.
