STIHL recommends the use of genuine
STIHL air filters. The high quality of
these parts will ensure troublefree
operation, a long service life for the
engine and extremely long filter life.
Exhaust emissions are controlled by the
design of the engine and components
(e.g. carburation, ignition, timing and
valve or port timing).
