Ducati Diavel Service Manual: Changing and cleaning the air filters
The air filter must be replaced at the intervals described in the "scheduled maintenance chart" (sect. 4 - 2).
Work on the vehicle right side, loosen screws (1) that secure the intake duct (2) to the filter box, and the radiator retaining screw (3); recover the washer (4).
Remove the intake duct (2).
Pull out the filter cartridge (5) from the seat in the airbox.
The filter cartridge can be cleaned with a jet of compressed air or replace if necessary.
Important
A clogged air filter will reduce air intake and engine power, increase fuel consumption and cause a build up of deposits on the spark plugs. Do not use the motorcycle without a filter as impurities in the air could get into the engine and cause damage.
Properly refit the cartridge in the filter box housing.
If the gasket (6) has been replaced, refit the new gasket in the proper seat (a) of the conveyor (2); place it so that the Tab (b) of the gasket (6) matches with slot (c) of the rh conveyor (2) as shown in the figure.
Note
Check for no abnormal wrinkles during gasket fitting.
Start the screws (1) and screw (3) with washer (4).
Tighten the screws (1) to a torque of 3.5 Nm +/- 10% (sect. 3 - 3Frame torque settings) and screw (3) to a torque of 10 nm +/-10% (sect. 3 - 3, Frame torque settings).
Important
If the motorcycle is used in very damp or dusty conditions, the air filter cartridge must be changed more frequently.
Check the air filter in the horizontal timing belt cover.
Loosen the screws (8) securing the central external cover (9) and remove it from the central side.
Loosen the screws (11) fixing the horizontal belt timing cover (7) and remove it from the horizontal cylinder assembly.

Once the check has been carried out refit filter (10), screw without tightening the screws (12) and refit the horizontal timing belt cover (7) on the horizontal cylinder assembly by tightening the screws (11) to a torque of 10 nm (min. 9 Nm - max. 11 Nm) for the plastic covers, and 6 nm (min. 5.5 Nm - max. 6.5 Nm) for the carbon ones (sect. 3 - 3, Engine torque settings).
Refit the central timing belt cover (9) by tightening the screws (8) to a torque of 10 nm (min. 9 Nm - max. 11 Nm) for the plastic covers, and 6 nm (min. 5.5 Nm - max. 5.6 Nm) for the carbon ones (sect. 3 - 3, Engine torque settings).
