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 Thread diameter: 10mm Threadreach: 19mm Seattype: flat Hexsize: 16mm Tipconfiguration: non projected Construction: 2 ground electrodes Terminaltype: Threaded-Terminal FITMENT KTM 400 EXC 2000-2002 KTM 400 LC4 SXC 2000-2001 KTM 400 MXC 2001-2002 KTM 400 SX 2000-2002 KTM 520 EXC 2000-2002 KTM 520 MXC 2000-2002 KTM 520 SX 2000-2002 KTM 950 Adventure/S 2003-2006 KTM 950 Super Enduro 2006-2009 KTM 950 Supermoto/R 2006-2007 KTM LC8 2003-2004 PROPOSITION 65 ⚠️WARNING This product can expose you to chemicals known to the State of California known to cause Cancer or birth defects and reproductive harm.
