The Mazda CX-5 is a popular compact SUV known for its impressive fuel efficiency, agile handling, and comfortable ride. However, like any vehicle, it requires regular maintenance to ensure optimal performance and longevity. One of the most critical components that need attention is the spark plugs. Spark plugs play a vital role in the engine’s combustion process, and worn-out or fouled plugs can lead to decreased fuel efficiency, rough idling, and even engine damage. In this article, we’ll explore when to change spark plugs in your Mazda CX-5, the importance of regular spark plug replacement, and some tips to help you do it yourself.

| Poor Fuel Efficiency | Decreased Engine Power | Rough Idling |
| Increased Emissions | Engine Misfires | Difficulty Starting |
Regular spark plug replacement can help prevent these issues and ensure your Mazda CX-5 runs smoothly and efficiently. It’s recommended to replace spark plugs every 30,000 to 100,000 miles, depending on your driving habits and the type of spark plugs used.
