When it comes to maintaining the performance and longevity of your vehicle, one of the most critical components to focus on is the spark plugs. Spark plugs are responsible for igniting the fuel-air mixture in your engine, which powers your car’s movement. Over time, spark plugs can become worn out and lose their effectiveness, leading to decreased fuel efficiency, rough idling, and even engine damage. In this article, we’ll explore the importance of changing spark plugs on a 2016 Nissan Altima and provide a step-by-step guide on how to do it yourself.
Why Change Spark Plugs?
Spark plugs are designed to last for a certain amount of time, usually around 30,000 to 100,000 miles, depending on the type and quality of the spark plugs. However, driving conditions, maintenance habits, and engine type can all impact the lifespan of your spark plugs. Here are some reasons why you should change your spark plugs:
- Improved Fuel Efficiency: Worn-out spark plugs can decrease fuel efficiency, causing your car to consume more gas than usual.
- Increased Engine Performance: New spark plugs can improve engine performance, giving you better acceleration and smoother idling.
- Reduced Emissions: Spark plugs play a crucial role in reducing emissions. Worn-out spark plugs can increase emissions, which can harm the environment and your car’s overall performance.
- Prevent Engine Damage: Ignoring spark plug maintenance can lead to engine damage, including engine misfires, rough idling, and even engine failure.
