The air flow meter is mounted in a light metal housing and is held in place by two spring clamps. The air intake hose is secured to the air filter with a clamp. The same fastening is used on the outlet hose between the air flow meter and the suction chamber. The filter element of the filter must be replaced in accordance with the instructions in the operating manual. When using the vehicle in dusty conditions, the filter must be changed more often.
To replace the air filter on a 16-valve engine:
- disconnect the wire from the "–" terminal of the battery;

- open the clip clamps (Fig. 132) and remove the air flow meter;
Fig. 133. Air filter mounting: 1 — air intake pipe; 2 - rubber band; 3 - air filter
- remove the air filter (Fig. 133). After loosening the hose clamp, remove the air intake pipe 1, unhook the rubber band 2 and finally remove the air filter 3. In this case, the pins come out of the rubber tips;
- remove the air outlet hose from the side of the filter.

Installation is carried out in the reverse order. Make sure that the guide pins enter both rubber tips (see Fig. 136) before putting on the rubber strip.
To replace the air filter on a V6 engine:
- disconnect the wire from the "–" terminal of the battery;
- remove the air flow meter plug between the filter housing and the air intake hose;
- disconnect the air outlet hose visible from the side;

- after loosening the clamp, remove the hose (Fig. 134);
- On a 272 kW engine, remove the wire plug from the exhaust pipe. On all vehicles, remove the wire plug from the intake air temperature sensor;

- loosen the hose clamp at the point shown in Fig. 135, remove the outlet hose and push it to the side;
- unhook the rubber band for fixing, disconnect the air inlet pipe from the filter and remove the filter. The filter is also held by two guide pins in rubber tips (Fig. 136).
Install in reverse order, making sure the guide pins fit into the rubber tips and that the exhaust duct is properly aligned.
