Spark plug NGK DPR8EIX-9 IRIDIUM with spark plug wrench socket magnetic

Time for a new spark plug? Spark plugs play a central role in the engine, as they are responsible for igniting the air-fuel mixture. Experienced mechanics recommend regular spark plug replacement, even if the plug isn't completely broken. Depending on the manufacturer and engine, modern spark plugs can last up to 60,000 kilometers before it's time for a replacement. If the spark plug looks charred, is smeared with oil, the contact is brownish, or has melted due to excessive temperatures, the spark plug needs to be replaced. Other signs that the spark plug needs replacing include misfiring, jerking while driving, reduced engine power, and increased fuel consumption. In the worst case, it can even cause the vehicle to break down. To avoid this, don't wait too long...
