INTAKE
AIR
FILTER: The air filtering element(s) on all naturally aspirated engines is polyurethane
foam
which
traps and holds dust and foreign matter which could be drawn into the engine and cause severe damage. Turbo
Charged and Turbo lntercooled engines only use a Mesh Screen.
By reason
of
the efficiency of the filter in trapping contaminants
it
is difficult
to
effectively clean the element.
It
isusually best
to
replace this low
-
cost item as occasion demands. Simply slide old element off its retaining screen
and carefully stretch a new element into position. If cleaning is desired, wash in a mild detergent mixed in clear,
sweet water.
DO
NOT wash in mineral spirits, varsol, gasoline, or any petroleum product.
