DENSO Auto Parts Spark Plug P/N:5391
DENSO Auto Parts 3051 spark plug for the 1983 Kawasaki KZ750F LTD Shaft and other vehicles ignites the air-fuel mixture in the cylinder. This DENSO Auto Parts spark plug is OE-grade, with one ground electrode in a standard configuration.
Hard starting, misfires or rough running can mean a plug is worn, though a weak ignition coil or a problem in the fuel supply can be behind the same symptoms, so find the cause before replacing plugs.
The 1983 Kawasaki KZ750F LTD Shaft, 1982 Kawasaki KZ750M CSR and 1980 Kawasaki KZ750G LTD II all fit this plug, along with more vehicles. Plug count varies by vehicle, with one plug per cylinder; the Kawasaki models named here take four. Owners of other bikes and cars can look up their own year and model in the "Vehicles it fits" section.
