Maintaining clean engine air filters is important for your engine's performance and health. As the engine air filters get dirty, their ability to air to flow easily suffers. Additionally, an old filter could start to fall apart and send dirt and debris into your engine. Porsche recommends you replace your engine air filters every 4 years or 40k miles (60k kilometers). This is a very easy DIY that even a beginner can do. It will also save you a lot of money versus going to a dealership. For an overview of how to perform this DIY procedure, check out the tutorial above from the YouTube channel, Cars+Raf. More detailed instructions can be found below.

These service instructions apply to:

  • 2005-2012 Porsche 987 Cayman Base / S / R, Boxster Base / S / Spyder

Tools and parts you'll need for the job:


  1. Ensure engine is not hot, so you can work comfortably.

  2. Gather tools and parts.

  3. Next, gain access to the engine:

    For the Cayman:

    1. Remove carpeted panel behind the seats  by prying up the edge towards the front of the car.

    2. Then lift and pull the carpeted panel out.

    For the Boxster, see video from Ry the car guy and instructions below:

    1. Lower your convertible top so it is approximately 24 inches from the top of your windshield​.

    2. At the base of the convertible top, there is a silver cable on each side that needs to be disconnected. Simply pry them off.

    3. Next, you will see that the base on the convertible top has a straight edge that is clipped in on both sides. Simply pull down on the straight edge to unclip this from the vehicle.

    4. Lift up the base on the convertible top. You should see a velcro tether on the base of the convertible top that you can use to keep it from falling.

    5. Now you should have full access to the carpeted panel above the engine. Twist the two plastic tabs 90 degrees to remove them. Then lift the carpeted panel out to reveal your engine.

  4. Open the rear trunk.

  5. Next, remove the metal engine cover by removing 5 T30 Torx screws.​

  6. Finally, you have access to your engine. Locate the engine air filter housing, which is located on the driver's side.

  7. Using a Philips tip screwdriver, remove the two screws to open the air filter housing.

  8. Remove the final Philips screw holding the air intake to the housing.

  9. Remove the old air filter and replace it with the new one.

  10. Re-install everything in reverse.

  11. Clean up your work area and return tools.

  12. You're all done!
