Notification
The Banks Ram-Air Filter comes 
pre-oiled and no oiling is 
necessary for initial installation.  
Service the filter as specified in 
this Section of the manual. 
1. Service Banks Ram Air Filter every 
50-100,000 miles on street-driven 
applications. Service more often in 
off-road or heavy-dust conditions. 
If an air-filter restriction gauge is 
installed, then clean the element 
when the air-filter restriction gauge 
enters the restrictive red zone. See 
Figure 54.
2. Use Banks Ram Air Filter cleaning 
system (part # 90094), available from 
Gale Banks Engineering to service 
the Air Filter. Follow the instructions 
included with the cleaning system 
to clean and re-oil your Banks Ram 
Air Filter. No gasoline cleaning, No 
steam cleaning, No caustic cleaning 
solutions, No strong detergents, No 
high pressure car wash, No parts 
cleaning solvents. Any of these No’s 
can cause harm to the cotton filter 
media plus SHRINK and HARDEN the 
rubber end caps.
CAUTION! Extremely fine dust 
from agriculture or off-road 
use will pull the oil from the 
element. Frequent re-oiling 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 
Ram-Air-filter cleaner and Banks 
Ram-Air-filter oil.
