Product Details
ThunderSpark Ignition Coils and Coil Sets are precision-engineered OE Replacement components designed to restore ignition system integrity and performance across modern gasoline engines. Each coil is built to match or exceed original equipment specifications for voltage output, resistance, and inductive response, supporting strong combustion under load. Constructed with high-dielectric epoxy, premium copper windings, and heat-resistant housings, these coils are built to handle the extreme temperatures and electrical demands found in today’s engine bays. Designed for exact OE fitment, they connect directly to factory harnesses and mount securely in place for coil-on-plug (COP), coil-near-plug (CNP), and distributorless ignition systems. Coil sets are available to simplify full engine service, reduce misfire diagnostics time, and improve overall ignition reliability. Whether replacing a single failed coil or refreshing the entire set during a tune-up, Walker Ignition Coils and Coil Sets deliver dependable spark performance, emissions compliance, and restored throttle response for everyday and high-mileage vehicles alike.
Description
Ignition Coils receive a signal from the distributor or engine control computer at the ideal time for combustion to occur and send a high voltage pulse to the spark plug to ignite the fuel air mixture in each cylinder.Application
