Fire every cylinder with a strong, precisely-timed spark — the ThunderSpark Ignition Coil 921-2145 drops in as a direct-fit replacement for the 2000-2003 Cadillac DeVille and Seville, the 2000-2002 Cadillac Eldorado (all V8-4.6L), and the 2001-2003 Oldsmobile Aurora (V8-4.0L).
An ignition coil takes its trigger signal from the ignition module or engine control computer and steps the 12-volt supply up into the high-voltage pulse that fires the spark plug, igniting the air-fuel mixture in the cylinder.
OE-level output: built to match or better the original equipment's voltage output, resistance, and inductive response for consistent spark.
Heat-tolerant construction: high-dielectric epoxy, copper windings, and a heat-resistant housing to handle the electrical and temperature demands of the engine bay.
Direct connection: designed to connect to the factory harness and mount in place for a hassle-free replacement.
Rugged build: made with quality materials to withstand harsh operating conditions for dependable service.
If a failed coil is the cause of misfires, rough idle, hesitation, or a check engine light, replacing it with 921-2145 helps restore proper spark to the affected cylinder; diagnose the cause before replacing. Country of origin: China. Manufacturer part number 921-2145 (also 9212145).
