Give each cylinder a fresh source of ignition with the SKP spark plug SP1037, an iridium spark plug built around an iridium core with a platinum tip. It is listed for many models, among them the 1999-2009 Chevrolet Silverado 1500 with the 4.3L engine, the 1996-1999 Chevrolet C1500 with the 4.3L, 5.0L or 5.7L engine and the 1996-1999 Chevrolet K1500 with the 4.3L, 5.0L or 5.7L engine.
A spark plug carries high voltage from the ignition system across its electrode gap. The resulting spark ignites the air-fuel mixture in the combustion chamber. Listed engines range from L4-2.0L to V8-7.4L. Examples include the V6-4.3L and the V8-4.6L.
Listed applications use 4, 6 or 8 plugs, depending on the engine. The minimum order quantity is one, so order the number your engine requires. Signs a spark plug may need replacing include misfires, rough idle, hard starting and hesitation on acceleration. These symptoms can have other causes, so diagnose the problem before replacing parts. See the "Vehicles it fits" section for the full list of vehicles and engines.
