Covering the ventilation housing in the engine bay, first remove the insulation blanket. After that, pull the two locking clips at the front and back of the ventilation housing apart, then slide the cover in the direction it should go to take it out. Take out the old
Air Filter and add a brand new air filter to the ventilation housing. Then, replace the ventilation cover housing and close the locking clips at both the front and back of the housing, so that the cover stays firmly against the tabs. At the end, return the insulation blanket to the ventilation housing.
