Filters

To start this blog off I will begin nice and easy, by showing you how to replace the two air filters located on the 98-05 3 series. If you can not accomplish this job you should probably not be underneath the hood of a car. I will start with the engine air filter, unhook the clips on the air box. Located where the yellow arrows are pointing. Then lift up on the upper portion of the box and pull the filter out. If the filter is dirty it should be replaced with a new one which can be obtained at any parts store. I would recommend Mann filters as they are a better quality. Next is the cabin air filter which filters out allergens, pathogens, and smells. Press down on the clips, located where the white arrows are pointed, and turn 90 degrees to undo them. Lift up the cover and check the underside of the filter as the air flows upwards. If the filter is dirty it should be replaced with a new one. To put the cover back on, press down on the clips and turn 90 degrees. You have now successfully changed your cabin air filter and engine air filter.
