You’ll Never Ignore These Spark Plugs & Coils—They’re Destroying Your Engine Performance! When it comes to maintaining peak engine performance, spark plugs and ignition coils often fly under the radar—even though they’re vital to your car’s power, fuel efficiency, and emissions control. Ignoring issues with these small but critical components can lead to major engine problems down the road. In this article, we break down why you can’t afford to overlook these spark plugs and coils—from performance drops and reduced fuel economy to costly repairs. ### Why Spark Plugs and Coils Matter More Than You Think Spark plugs are responsible for creating the spark that ignites the air-fuel mixture inside your engine’s combustion chambers. Meanwhile, ignition coils step up the voltage from your car’s battery to generate that spark. Together, they determine how smoothly and efficiently your engine runs. Over time, these parts wear out due to heat, pressure, and exposure to engine byproducts—yet many drivers only notice problems once serious damage has occurred.
