Filters

AIR FILTER

An engine requires clean air to function efficiently. They help filter/clean outside air of damaging debris such as dust, grit and pollutants before entering the engine. Clean air helps the engine ‘breathe’ easier, which can enhance both engine performance and efficiency.

Common Signs your Air Filter may need Replacing

Filter Appears Dirty

If your filter visually appears dirty (caked with dirt, dust and debris), it’s time for a filter change.

Exhaust Pipe emitting Black Smoke

When the engine is not receiving clean air (dirty filter) the air/fuel mixture may not burn completely during the combustion process. This can result in the unburned fuel exiting the exhaust pipe as black smoke.

Check engine light comes on
A dirty air filter can cause your ‘Check Engine’ light to appear, from a buildup of carbon deposits – lack of clean air to the engine.

CABIN AIR FILTER

This filter screens airborne dust, pollen and other airborne particles from entering the inside of the vehicle through the heating and air conditioning systems. When the filter becomes blocked with contaminants, air flow from the heating/cooling system may work less efficiently.

Common Signs the Cabin Air Filter may Need Replacing:

Filter Appears Dirty

If your filter visually appears dirty (caked with dirt, dust and debris), it’s time for a filter change.

Insufficient Air Flow

When the cabin air filter is dirty, air flow may become restricted and air coming from the interior vents may have less force.

Odors From Vents

A contaminated cabin air filter may emit a dusty/musty odor, which becomes stronger when the ventilation system (heat/cool) is turned on.

EXPERT TIPS

• The frequency at which an air filter and cabin air filter needs to be changed depends on mileage and the environment, such as dusty roads or extended idling.
• Ensuring your air filter is changed when dirty is an inexpensive way extend the life of the engine.
• Motorcraft® filters are application specific – not “one size fits all”.
• Refer to your Owner’s Manual and Ford Maintenance Schedule for specific information and recommendations on when to replace your filters.
