✓【 WHY REPLACE YOUR IGNITION COILS 】 On V8 engines, under-hood heat often exceeds 300°F, degrading ignition coils over time. Replacing your ignition coils restores the entire ignition path—eliminating misfire codes (P0300–P0308), rough idle, hesitation, and cold-start stumbles. It's a complete cure, not a band-aid.
