Air filter
Air filter dry type, with thermostat, with replaceable filter element. The filter housing is mounted on four carburetor studs, sealed with a rubber gasket and fastened with self-locking nuts. The filter element, interchangeable with the filter element of the VAZ-2121 engine, is made of special cardboard with a precleaner. The filter housing has an air intake pipe, on which the thermostat is attached with a coupling bolt.
Thermostat
The thermostat allows you to maintain the temperature of the air entering the air filter within 25-35°C. A cold air intake made of polypropylene to reduce noise is put on the front pipe of the thermostat housing. The lower branch pipe of the thermostat is connected by a corrugated hose to the warm air intake, which takes air from the exhaust manifold area. A damper is installed in the thermostat housing, which is pivotally connected to the thermo-force element. The damper automatically regulates the air flow into the air filter depending on the temperature of the thermal force element. On some series of cars there may be thermostats with manual adjustment of the damper position.
