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.
