The air filter in your car is used to clean the air which enters the engine
while it is running and producing power for the car, truck or SUV. Positioned in
plain sight, the filter is inside the filter housing which is attached
to the intake tube and then to the throttle actuator of the engine where the
cleaned air enters the engine.
Most people do not realize the importance of the
air cleaner because they do not know how much air the engine processes under
normal running conditions, trust me, it's a lot.
Please watch the video below

A vehicle's engine air filter is a replaceable cleansing unit. In most cases
a filter can be replaced in under 15 minutes. The filter should
be changed between 6,000 and 12,000 miles depending on how dirty the roads are
in which the vehicle is driven on. Never have a repair garage or the dealer
replace it, if you do it yourself you can treat yourself to a nice night out
with the money you save, and the parts are easy to get either at
Amazon or your local auto parts store.
There are many levels of quality when it comes to filters you want to get the
OEM (factory) unit, it costs a little more, but it is the best way to protect
your investment. If you choose a cheap filter you may be allowing dirt particles to enter the engine which
can cause premature wear and could possibly lead to a catastrophic engine
To determine if your filter needs to be changed remove the filter housing, it
is held together by either retainer clips or screws. Once you have the housing
off remove the filter and gently tap it on the ground
while watching for dirt or particles, if you can
see dirt and particles coming off of the filter it means it is filled to
capacity and replacement is needed.
When the filter plugs up due to non-maintenance it causes low engine power,
the good news is this problem is easy to fix. Replacing the filter should be included in your regular
maintenance regiment of changing the engine oil or a tune up.

Locate the filter housing it is
connected to the air intake tube and follows to the throttle
actuator of the engine. This housing holds and seals the filter in place
to prevent unfiltered air to bypass which would allow dirt into the engine.
Sometimes the housing will be located either on the right or left side of the
engine bay and mounted to the fender or on the engine itself such as in the
