WARNING! If your veh icle has a Vehicle Emission Contr ol Infor mation decal affixed to the factor y air box, a n ew rep lacement label must

be obtained and installed in a readily visible position in the engine compartment in order to remain CARB compliant. Failure to do so will prevent
the vehicle from passing a smog check. Replacement labels can be ordered from your local dealership. Regulations state that the VECI label shall
not be affixed to any equipment which is easily detached from the vehicle. Label placement, under the hood on a painted surface is recommended.

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.
