DENSO Auto Parts Spark Plug P/N:3370
DENSO Auto Parts 3110 spark plug for the 1959-1961 Chevrolet Impala V8 5.7L and other vehicles ignites the air-fuel mixture in each cylinder. This DENSO Auto Parts spark plug is OE-grade.
Hard starting, a rough idle or a misfire can mean the plugs are worn, though a weak ignition coil or a damaged plug wire can be behind the same symptoms too, so find the cause before you replace anything.
The 1959-1961 Chevrolet Impala V8 5.7L and the 1961 Chevrolet Suburban V8 5.7L take this spark plug, and so do more vehicles; the two V8s take eight plugs apiece. It is also a spark plug for the 1980-1983 Volkswagen Vanagon H4 2.0L, which takes four. Open the "Vehicles it fits" section to check your exact model and engine.
