BMW and MINI Engine Air Filter Replacement and AFE Install
Most BMW and MINI air filters are enclosed in a plastic or metal filter housing (or box). On most models, the filter is accessed by separating the upper and lower (or left and right) halves of the housing, secured to each other via a number of spring clamps. Some models have a slide-out tray for the filter and some models secure the housing together with screws. Follow along (below) as we replace the air filter on a BMW 3 series 99 thru 05 (E46 chassis), or watch the video at blog.bavauto.com. The applicable Bentley, Haynes or Chilton repair manual will show the details for your year and model. In this example, we’ll be installing a reusable (no-oil) aFe ProDry S filter.
