Built strictly to factory dwell time, heat range, and connector specsno check-engine lights, no reflash needed.; WHY REPLACE YOUR IGNITION COILS & PLUGS TOGETHER On L4 engines, under-hood heat often exceeds 300°F, degrading ignition coils and widening plug gaps over time. Replacing both together restores the entire ignition patheliminating misfire codes (P0300P0304), rough idle, hesitation, and cold-start stumbles. It's a complete cure, not a band-aid.; INSTANT PERFORMANCE GAINS & BETTER FUEL ECONOMY Upgrade your drive with our ignition coils that maintain stable voltage under high loads.
