A failing ignition switch often results in the car not starting (no power to the dash lights or starter), or accessories cutting out while driving. Failing ignition coils typically cause engine misfires, rough idling, poor acceleration, and the 'Check Engine' light to illuminate.
While you only need to replace the faulty coil, many mechanics recommend replacing all coils and spark plugs simultaneously, especially if they are high-mileage. This ensures uniform performance and prevents sequential failures, saving you labor costs in the long run.
Dielectric grease is a non-conductive compound applied to electrical connections, particularly spark plug boots and coil terminals. It seals out moisture, dirt, and corrosion, preventing voltage leaks and ensuring a strong, consistent spark.
Replacing the electrical portion of an ignition switch is often manageable for DIYers. However, replacing the mechanical lock cylinder can be complex, sometimes requiring specialized tools or programming (especially in newer vehicles with transponder keys). Always consult your vehicle's repair manual.
Ensuring your vehicle starts reliably depends entirely on a healthy ignition system. By selecting high-quality replacement parts—whether it's a critical ignition switch, a set of high-output coil packs, or essential tune-up grease—you invest directly in your vehicle's longevity and performance. Browse our top picks today to find the perfect replacement component and restore your vehicle's starting power with confidence.
