Importance of air filter maintenance
A clean engine runs more efficiently than a dirty engine and your car’s air filter is the engine’s first line of defense. A new air filter allows your vehicle’s engine to get clean air, a key component in the combustion process. The air filter prevents airborne contaminants such as dirt, dust and leaves from getting pulled into your car’s engine and potentially damaging it.
What if you delay changing your air filter?
Putting off your air filter change can lead to problems with your engine. You might notice a decrease in gas mileage resulting in more trips to the gas station. As a result, if your engine doesn’t get the required amount of clean air, it won’t perform properly. Reducing air flow can lead to fouled spark plugs which can create engine misses, rough idling and starting problems. Long story short, do not delay replacing your air filter.
