NGK Spark Plug P/N:DR8HS
NGK BR8HS spark plug for the 2008-2009 Hyosung SF50B/Prima 49cc and other vehicles fires the air-fuel mixture in the cylinder with a spark. Among NGK spark plugs, it is made for OE applications and comes in the yellow box packaging.
Hard starting, a misfire or a rough idle can mean a worn plug. None of these signs proves the plug is at fault, since a tired ignition coil could be behind them too.
The 2008-2009 Hyosung SF50B/Prima 49cc, the 2008-2009 Hyosung SF50R/Rally 49cc and the 2002-2005 Yamaha SJ700 Super Jet all take this plug, along with many other vehicles and watercraft. Each Hyosung takes one and the Yamaha takes two; this listing is one plug.
