DENSO Auto Parts Spark Plug P/N:4130
DENSO Auto Parts 6001 spark plug for the 1969-1972 Kawasaki H1 Mach III and other vehicles ignites the air-fuel mixture in the cylinder. The DENSO Auto Parts spark plug is OE-grade, and its special ground electrode configuration is OEM specified.
A worn plug can show up as hard starting, a misfire or rough running, and a worn or fouled electrode is visible with the engine off and cool. A misfire or hard start does not by itself show the plug is at fault; a weak ignition coil is another common source. This listing is one plug.
This spark plug fits the 1969-1972 Kawasaki H1 Mach III, which takes three, and the 1967-1971 Kawasaki A1 Samurai and A1SS, which take one each. To see whether your own bike is covered, look it up in the "Vehicles it fits" section of this page.
