The air filter is installed in the engine compartment and fixed on rubber supports.

The filter element of the air filter is paper with a large area of the filter surface.

The outside air is sucked in through the air intake pipe located at the bottom under the air filter housing.

Then the air passes through the filter element of the air filter, the mass air flow sensor, the intake pipe hose and the throttle nozzle.

After the throttle pipe, the air is directed into the channels of the receiver and the intake pipe, and then into the cylinder head and into the cylinders.
