Car engines need an unobstructed inflow of fresh oxygen. The air filter prevents dust, dirt, sand, insects, and other debris from coming into the engine along with the air. But over time, car air filters become clogged up and can start to restrict the inflow of oxygen, which can lead to engine problems. Here are a few signs that you might need to replace your air filter soon at your local Ford dealer, Hutch Ford.
Misfiring Spark Plugs
When a clogged air filter prevents sufficient fresh oxygen from entering the engine’s combustion chambers, the fuel-air mixture becomes unbalanced. The excess fuel will start to create a sooty residue that can coat and foul the spark plugs, preventing them from firing effectively. This leads to misfiring, which will cause your engine to cough and sputter, especially when idling.
Diminished Engine Power
An engine that’s starved of oxygen by a clogged air filter will rapidly lose power. You may find it harder to maintain high speeds on the highway or accelerate promptly when trying to overtake another vehicle.
Falling Fuel Economy
For optimal combustion efficiency, a car’s engine needs an ideal balance of air and fuel. When the air gets restricted, overall fuel efficiency falls, and you’ll find yourself stopping more frequently at the gas station.
Black Exhaust Smoke
Clogged air filters can also lead to black smoke emerging from the vehicle’s tailpipe. This smoke is created by excess unburned fuel escaping back into the exhaust system and partially igniting on its way out.
Check Engine Light
The variety of engine problems created by a blocked air filter will soon be picked up by your car’s sensors. This will trigger the check engine warning to light up on your dashboard. It’s best to have a technician take a look whenever you see this warning light.
Filthy-Looking Air Filter
If you suspect a clogged air filter, you can visually check it yourself. Pop the hood and locate the large cold air collector box, which is usually near the front of the engine compartment.
Inside the box, you’ll find the filter. Check between the filter’s pleats. If the filter is clearly discolored with large patches clogged up with dirt and grime, consider having it replaced.
How Often to Replace Your Air Filter at Hutch Ford
For the majority of drivers, the air filter will need to be replaced once every 12,000 to 15,000 miles. This usually equates to about once a year. If you drive in particularly dusty or dirty conditions, you’ll need to have it replaced more frequently.
