Regular air filter changes have at least five advantages: higher fuel economy, lower emissions, faster acceleration, longer engine life, and better overall driveability. The engine can utilize up to 10,000 gallons of air for every gallon of fuel used, therefore it is simple to see how important a clean air filter is to the correct operation of an automobile.
- Enhanced fuel economy
one of the main justifications for routine air filter replacement. According to some studies, replacing a dirty air filter can enhance fuel economy on older, carbureted cars by up to 14 percent. This is true if the filter is so filthy that it impairs driveability. On contemporary fuel-injected cars, changing a blocked air filter may also boost acceleration by 6 to 11%. According to other research, fuel savings of up to 15 per gallon and an increase in gas mileage of 10% are possible. Regardless of the precise numbers, it is clear that a clean air filter enhances engine air flow, boosts engine performance, and improves gas mileage.
- Lessening of emissions
Clogged air filters can choke the engine by reducing air flow, which has a negative impact on the car’s pollution control systems. This results in an inaccurate air-fuel ratio and spark plug ignition troubles, both of which can seriously impair driveability. Spark plugs can clog, which frequently causes an engine miss or rough idle and significantly reduces fuel efficiency. Additionally, it may result in the “Service Engine Soon” light turning on and increase engine deposits brought on by having an excessively rich fuel mixture. The engine can work effectively with increased air flow, which lowers emissions and fuel consumption.
- Increases engine life:
Because the air filter is made to collect harmful dirt and debris that might harm internal engine parts like the cylinders and pistons, routine air filter replacement helps extend engine life. Even the smallest salt grain-sized object can cause engine damage, necessitating expensive repairs.
4. Inexpensive and quick fix:
One of the cheapest maintenance items to change is an air filter, and you can do it yourself. Make sure the replacement air filter is made specifically for your car’s make and model. The air filter is typically found around the top front or side of the engine by the throttle body on more recent fuel-injected vehicles. The rectangular air filter is housed in a container made of rectangular, black plastic, and is typically secured shut with clips or screws. On older cars with carburetors, the air filter is a circular metal box that sits above the carburetor and is fastened by a wing nut.
- easy to follow
Every 12,000 to 15,000 miles, or more frequently in dusty driving conditions, air filters should be changed. The frequency of air filter replacement will be specified in the owner’s handbook maintenance program. Even though an air filter seems to be clean, it should still be changed when advised.
A replacement air filter will boost fuel economy, lower emissions, enable ideal air flow, and enhance engine performance. Changing your air filter on a regular basis will also guard against excessive wear and damage that could lead to expensive engine repairs as well as concerns with driveability.
