A dirty air filter can reduce the amount of clean air that reaches the engine, resulting in a decrease in power and performance. Replacing the air filter with a new, clean one can improve engine acceleration. Aftermarket air filters can lead to increases in engine performance and fuel mileage rating, although these may be more noticeable on older cars. For newer models, some “performance” air filters may only make a negligible difference.
A dirty air filter reduces the amount of air supplied to the engine, leading to an increase in unburned fuel that becomes soot residue. This soot can build up on the tips of the spark plugs, making them unable to produce a proper spark. This can cause your car to move sharply, idle, and in some cases, the engine may fail. If your acceleration seems slow or your car responds slower than normal, it could be due to oxygen starvation.
If you find that your air filter needs a change, it is advisable to also check the condition of the spark plugs to see if they have also suffered any damage. You may even experience a slight hiss if airflow is limited due to excessive buildup on the filter screen. Once an air filter is too clogged and no longer working, it can lead to decreased car performance and even engine damage. Air filter replacement can be part of a general tuning service that will help you get better mileage and performance out of your vehicle.
By providing clean air flow to the engine, an air filter ensures that the engine receives the correct amount of air needed to operate at its maximum level. A new air filter will increase fuel consumption, reduce emissions, allow optimal airflow and improve engine performance. Over time, as dust and dirt build up, the air filter will darken and dirt will be noticeable. With inadequate air supply, unburned fuel leaves the engine and may not produce smoke or flames in the process. When replacing an air filter, some people opt for non-standard aftermarket air filters to help improve the performance of their car.
For that chemical reaction to occur, the engine needs a constant supply of oxygen for the fuel to burn properly. An air cleaner is one of the most economical maintenance components to replace and you can do it yourself. The air filter replacement cost varies depending on the model of the car and where you ask for help. The cabin air filter is used regardless of whether or not you use the air conditioning or heating in your car, since there is always air entering and leaving the passenger compartment. Therefore, for safe and optimal performance of your engine, make sure to address dirty air filter symptoms immediately and always have a clean air filter in place.
