aeroSol oilinG
after cleaning air filter
always reoil before using.
spray banks ram-air filter
oil down into each pleat
with one pass per pleat.
Wait 10 minutes and
re-oil any white spots still
showing.
oilinG hintS
never use a banks ram-air filter without oil
(the filter will not stop the dirt without the oil). use
only banks ram-air filter oil. banks air-filter oil is a
compound of mineral and animal oil blended with
special polymers to form a very efficient tack barrier.
red dye is added to show just where you have applied
the oil. eventually the red color will fade but the oil
will remain and filter the air. neVer use automatic
Transmission fluid. never use motor oil. never use
diesel fuel. never use Wd40, lps, or other light-
weight oils.
reinStall
reinstall your banks ram-air filter element with
proper care. make sure the element seats properly in
the filter case. Install the cover making sure it’s in the
right position. Tighten all the nuts, bolts, screws or
clips to factory specifications.
do not diScard
affix the “do not discard” sticker to the filter
case (included with every banks replacement element).
make sure you put the sticker in a highly visible place
to alert your mechanic not to discard.
PerFormance hintS
service every 50-100,000 miles on street-driven
applications. service more often in offroad or heavy-dust
conditions. If an air-filter restriction gauge is installed,
then change the element when the air-filter restriction
reaches 18”/h
2
o.
caution! extremely fine dust from agriculture or
offroad use will pull the oil from the element. frequent
reoiling of the element’s clean side might be required.
completely service when practicable. for extra
protection use an air-filter sealing grease on rubber
ends of the element. service only with banks air-
filter cleaner and banks air-filter oil.
