3. Pull the air cleaner/filter box cover out and remove
the air filter element from the air filter box. If the
element is dirty, you should replace it. If the element
is only dusty, it may be cleaned by blowing
compressed air through it from the clean side. Make
sure you are away from your engine compartment
when cleaning the air filter with compressed air.
