Cleaning And Changing Air Filters - Ducati ST4S Owner's Manual

Cleaning and changing air filters

Replace air filter at the required intervals shown in the
routine maintenance chart (see Warranty Card). The air
box is accessible after lifting the fuel tank.
Undo the clips (1, fig. 52) of the cover on both sides of
the air box, then remove cover (2).
Remove the filter (3, fig. 53) and fit a new one.
Important
A dirty filter will reduce air intake, increase fuel
consumption, reduce engine power, and foul the spark
plugs. Do not use the motorcycle without filter or
suspended matters could get into the engine and cause
damage.
Install the filter properly into its seat in the air box as
shown in figure 53 and refit all the parts you have
removed.
Important
If you are using the motorcycle on dusty or very
wet roads, replace filter more frequently than
recommended intervals (see Warranty Card).
