An unexplainably louder-than-usual engine.. A noticeable lack of power.. A significant drop in RPMs while accelerating for no apparent reason.. A blinking or intermittently activating check engine light.. An active gas warning light when the vehicle has plenty of gasoline.. How often should coil packs be replaced?Generally speaking, coil packs last up to 5 years or 120,000 miles before they require replacement. Coil packs will last a long time but their continued exposure to heat and friction can naturally wear them down. The coil pack can also become damaged by carbon accumulation.
Do upgraded coil packs do anything?Whether working with coil packs or traditional canister style coils, the advantage of an upgraded coil makes for a hotter spark. Intensifying the heat makes it easier to burn the fuel and air mixture. This translates to improved performance.
