DENSO Auto Parts Spark Plug P/N:3143
DENSO Auto Parts 6008 spark plug for the 1969 Chevrolet C10 Pickup V8 5.0L and other vehicles ignites the air-fuel mixture in each cylinder. The plug is OE-grade.
Worn spark plugs can show up as hard starting, a misfire or a rough idle. A weak ignition coil, a bad plug wire or a fuel-delivery fault can be behind those signs too, so find the cause before you buy plugs.
The plug is listed for a wide range of models, including the 1969 Chevrolet C10 Suburban V8 5.0L and the 1969 Chevrolet C20 Pickup V8 5.0L. A V8 here takes eight plugs. Open the "Vehicles it fits" section to check your exact model and engine.
