Spark Plugs & Coils That Keep Your Engine Running—This Map Will Change Everything! When it comes to keeping your engine humming efficiently, two critical yet often misunderstood components are spark plugs and spark plug coils. These small but powerful pieces are essential for reliable ignition, smooth performance, and optimal fuel efficiency. But with endless options on the market, choosing the right spark plugs and coils can feel overwhelming. That’s where this exclusive diagnostic map comes in—your go-to guide to diagnosing and fixing common timing and ignition issues with precision. ### Why Spark Plugs & Coils Matter Spark plugs ignite the air-fuel mixture inside your engine’s combustion chamber, while spark plug coils generate the high-voltage spark needed for combustion. Over time, these components wear out due to heat, friction, and carbon buildup—causing engine misfires, poor fuel economy, rough idling, and even withdrawal from performance.
