This is a O.S. Air Filter specially designed to extend the life of high
performance buggy engines. Each filter element has been pretreated with a
special lubricant which traps fine dust particles and keeps them from damaging
the engine. This reduces engine wear and assures reliable performance and
longer engine life.
Includes: One rubber mount tube
Two pretreated foam elements (OSMG2389)
Comments: This is for the .21 size (primarily the .21 RX-R), can be used on
other .21 On-Road engines.
