NGK NGK Standard Spark Plug P/N:5946
NGK 3437 spark plug for the 1996-2009 Kawasaki EN500C Vulcan 500 LTD 499cc and other vehicles fires the air-fuel mixture in the cylinder. Like other NGK spark plugs, it is engineered for OE applications.
A worn plug can show up as hard starting, a rough idle or a misfire. Before you replace the plugs, rule out a weak ignition coil, a damaged plug cap or wiring, and a fuel or air supply problem, which can look much like a worn plug. The number of plugs needed varies by engine.
3437 also fits the 1997-2009 Kawasaki EX500 Ninja 500R 498cc and the 2003-2004 KTM 660 Rally 654cc, along with a wide range of other vehicles. Open the "Vehicles it fits" section to check your exact model and engine.
