Fitting BMC Performance Air Filter to Mini Cooper S

  1. Locate the air filter box at the top right side of your engine.
  2. Unplug the Mass Air Flow Sensor (MAF).
  3. Loosen the clamp that connects the intake tube to the air box using a flat head screw driver. Once loosened, the intake tube should easily move away from the air box.
  4. Using a 10mm socket wrench and Philips head screw driver, remove the nuts and bolts that hold the airbox housing together.
  5. Remove the air box housing and air filter. They should easily pull away, if you are tugging- something hasn’t been loosened properly!
  6. Drop in the new BMC Performance Air Filter.
  7. Repeat steps 1-5 in reverse order.
  8. Enjoy the new-found performance of your Mini Cooper S!
