For your Oiled media filter we

suggest using the AIRAID Filter

Tune-Up Kit!

Synthamax Air Filters do not re­quire oil. Service air filter as need­ed by cleaning with common non­petroleum all-purpose household
cleaner and water. Simple Green®,
Formula 409® or equivalent works
great. Apply cleaner to outside of
air filter and allow to soak. Then
flush filter clean from the inside out
with a garden hose and repeat steps
if necessary. Do not apply high
pressure water or air to clean filter.
Allow filter to air dry and reinstall.
