The replacement interval depends heavily on the type of plug. Copper plugs usually need replacement every 30,000 miles. Platinum plugs typically last 50,000-75,000 miles, and high-end Iridium plugs can last 100,000 miles or more. Always check your vehicle's owner manual for the specific maintenance schedule.
Common symptoms include engine misfires (rough idling), difficulty starting the engine, poor acceleration, reduced fuel economy, and the illumination of the Check Engine Light (CEL).
Most modern Iridium and Platinum spark plugs come pre-gapped from the factory to the most common specifications. While it is generally recommended not to adjust the gap on fine-wire plugs to avoid damaging the tip, you should always verify the gap against your vehicle's specification before installation.
While coils generally last longer than plugs, it is often recommended to replace them together, especially if your vehicle has high mileage (over 100,000 miles) or if you are experiencing misfires. Replacing them as a set ensures the entire ignition system is optimized for performance.
Choosing the best spark plugs and ignition components is a straightforward way to restore or enhance your vehicle's efficiency and power.
