Our recommendation for replacing spark plugs is every 4 years, or 60 000 kilometers. 

Over time, spark plugs wear out, which can result in reduced engine performance, such as decreased power and acceleration, rough idling, and poor fuel economy. 

Worn or fouled spark plugs are a common cause of engine misfires, which can cause engine hesitation, rough running, and even damage to the catalytic converter over time. 

By replacing worn spark plugs, you can help maintain optimal fuel efficiency and save money on fuel costs in the long run. 

Prolonged use of worn spark plugs can lead to increased wear on other engine components, such as the piston rings and valves. Faulty spark plugs can make it difficult to start your vehicle, especially in cold weather. Replacing spark plugs at regular intervals is a relatively simple and inexpensive maintenance task that can have a significant impact on the overall health and longevity of your vehicle.
