Spark Plugs
Spark Plugs: Varies by Vehicle
What? Spark plugs are essential engine components that ignite the air-fuel mixture within the combustion chamber. While traditional designs utilized copper, modern high-performance plugs are engineered with advanced metals capable of enduring extreme, repeated heat.
Why? They are the primary trigger for engine combustion. Modern materials allow for significantly improved durability, enabling these plugs to maintain performance for over 100,000 miles, whereas older copper-based designs have a lower heat tolerance and require more frequent maintenance.
When? Replacement intervals vary based on the plug material and vehicle engine design. To ensure optimal performance and engine longevity, always follow the specific replacement mileage intervals outlined in your vehicle manufacturer’s guidelines.
