How Often Should You Replace Your Spark Plugs?
As the component that ignites the mix of fuel and air in the cylinders of your engine, the spark plugs will get and keep your car going.
This crucial role means that it’s important to ensure that they remain in good condition and to replace them before they deteriorate and cause more costly engine repairs. Here are some pointers to help you to judge when the time is right to contact your Porsche dealer for an inspection.
Age and Mileage
Plugs are designed for long-term durability, and could well outlast your car. However, they experience wear with engine use and are more vulnerable to car usage than to age, so mileage is an important factor when thinking about a replacement. Also, be aware that the advice varies depending on the age of the car. For models dating back to before 2002, a plug replacement is recommended every 24,000 miles or two years.
This interval is longer for later models, at every 40,000 miles or 4 years. But it’s important to read your owner’s manual carefully for their recommendation and to stay alert to other factors. Damaged plugs will have an increasing impact on your engine power and fuel efficiency, so it pays to make sure that they’re kept in tip-top condition.
Other Problems
Problems with other components of your car might have a knock-on effect on the efficiency of the plugs. For example, a clogged air filter, malfunctioning catalytic converter, overheating, and oil contamination will all cause damage and shorten their lifespan. If your car has suffered from any of these difficulties recently, then it might be sensible to get the plugs checked as well.
Signs of Trouble
If the plugs are malfunctioning or damaged then your car will give you some clues. All of the following problems might be an indication that your engine just isn’t getting that spark:
- The engine misfires, surges, or momentarily cuts out
- Rough and uneven idling, with heavy vibrations and jittering
- Difficulty starting the engine
- Unresponsive or sluggish acceleration
- Loss of fuel efficiency
- Check engine light appears
If you experience any of these issues then your plugs could be to blame, and it’s time to schedule a diagnostic checkup. As a Porsche owner, we know how much you value your driving experience and care for your car, so you don’t need to be reminded about the importance of good maintenance. But with so many variables at play with the plugs, it can be difficult to know when you should think about a replacement.
