Air in the Side, out the End
(standard flow filters)
When spec’ing an
Air Cleaner . . .
Determine the airflow
requirements of your engine, then
find the corresponding cfm airflow
in the table at right. The restriction
numbers (shown in inches of
water) indicate the approximate
initial restriction of each model air
cleaner at that cfm. If there are
two air cleaner models that fit your
parameters, choosing the one with
the lower restriction will provide
longer filter service life. When
calculating total initial restriction of
the entire air intake system, include
the restriction caused by ducting,
elbows, pre-cleaners, etc.
