286 MAINTAINING YOUR VEHICLE
NOTE: The air filter housing contains a Mass Air Flow
sensor. This sensor is critical to proper engine operation
and component longevity. Any damage or modification
to this sensor could result in major engine and/or
exhaust aftertreatment damage. We recommend you use
MOPAR® brand parts.
Even though your vehicle is equipped with an Air Filter
Monitor, a visual inspection of the air cleaner filter
element is recommended every 15,000 miles (24,000km)
or 12 months – whichever occurs first. Under no circum-
stances should the air cleaner filter element exceed
30,000 miles (48,000 km) or 24 months, whichever comes
first.
CAUTION!
Many aftermarket performance air filter elements do
not adequately filter the air entering the engine. Use
of such filters can severely damage your engine.
Engine Air Cleaner Filter Inspection and
Replacement
Inspect engine air cleaner filter for dirt and or debris, if
you find evidence of either dirt or debris you should
change your air cleaner filter.
