  • Correct air filter for your engine

Step by step

  1. Open the airbox: usually clips, sometimes screws.
  2. Note the orientation of the old filter and remove it.
  3. Wipe or vacuum out leaves and dust from the airbox. Don't let debris fall into the intake duct.
  4. Fit the new filter with the seal seated all the way round.
  5. Close the airbox and make sure all clips are secured and the duct to the MAF sensor is tight.

Safety: An air leak after the filter lets unfiltered air into the engine and can upset the MAF sensor.
