Air filter

Only air filters approved by ROTAX are permitted for use. The air filters
specified by ROTAX are special K & N air filters. Dry filter elements of
paper are not allowed for humid operating conditions, as they absorb
water, thus reducing the air intake leading to enrichment of the fuel/air
mixture.
Two kinds of filter design are applied on these engines:
- Single air filter
- Double air filter
With 2 carburetors on engine, either 2 single air filters or 1 double air filter
may be fitted.
■ WARNING:
Always secure air filters against loss.
