•  Filtration is an important component to the life of a vehicle.
•  Engine air filters remove dirt, dust and other contaminants from the
engine intake before it reaches vital engine parts like cylinder walls,
pistons and piston rings.

An Air Filter’s Job is to Clean All that Air
Before it Reaches the Engine.
•  There are three primary filters on a vehicle that protect and optimizes
performance. These are Fuel, Oil and Air Filters.
•  The most critical being the air filter. The common types of vehicle air
filters are panel and round.

Most Customers Do Not Realize the Importance of
a Clean Engine Air Filter
•  Changing the air filter should be part of a routine maintenance schedule.
•  Show and compare a clean engine air filter to a dirty filter.
•  A clogged engine air filter can hinder the fuel to air ratio needed for the best
engine performance.
•  Changing their engine air filter can keep contaminants from damaging vital
engine parts.
•  Sluggish performance or loss of engine power is a strong indicator of a need for
an air filter change.
The Filter Manufacturer's
Council recommends
inspecting the air filter every
time the oil is changed (every
three to six months), and
replacing every 12,000 miles
for preventive maintenance.

How to Service: The Do’s
•  Follow your owners manual instructions – The vehicles manufacturers instructions
on filter installations and scheduled maintenance are important to the life of your
vehicles engine.
•  Always clean the inside of the
housing carefully - Dirt left in the air
cleaner housing can damage your
engine. Use a clean, water-dampened
cloth to wipe every surface clean.
Check it visually to make sure it’s
clean before putting in a new element.
•  Always clean the gasket sealing
surfaces of the housing - An
improper gasket seal is one of the
most common causes of engine
contamination. Make sure that all dirt
is completely removed, both on the
bottom and top of the cleaner.

•  Check for uneven dirt patterns on your old element - Your old element is a
valuable clue to dust leakage or gasket sealing problems. A pattern on the element
clean side is a sign that the old element was not firmly sealed or that a dust leak
exists. Make certain the cause of that leak is identified and rectified before
replacing the element.
•  Inspect your filter - The correct way to inspect a panel air filter, or a round air filter
in an older vehicle, is to remove the filter from its housing and hold a shop light
behind it. A little discoloration is normal, but if the filter is dark and blocks the light,
it is overdue for a change.
•  Look for any imperfections - make sure the new filter has a good seal and there
are no visible gaps or uneven breaks or dents in the media or gasket seals.

How to Service: The Don’ts
•  Don’t overlook a worn or damaged gasket in the housing - If your
cleaner has a cover gasket, replace it with a new one. Always check to
be sure no piece of the old gasket is worn. If your filter model calls for a
new gasket with each use, never reuse the old one.
•  Never rinse, shake or rap an element to clean it - Rapping hard
enough to knock off dust often damages the element and destroys your
engine protection. Deeply embedded dirt is never released by tapping.
This is not a good cost saving method to reuse an old filter.
•  Don’t use a dented filter element - Never install a dented or punctured
element, because it cannot protect properly against contamination. A dent
can make a firm seal impossible or can indicate damaged media.

How to Service: The Don’ts
•  Never use a warped cover on a housing - Replace with a new cover as
soon as possible. A warped or damaged cover cannot make a proper
seal. Also check to make sure there is not damage to the air cleaner
housing that could cause a leak.
•  Never substitute an incorrect element model number - Elements may
look almost identical but can differ by a fraction of an inch in length difference that makes a positive firm seal impossible. You’re always better
off referencing the Znet/AutoZone Filtration Catalog for proper filter
specifications and correct application.
