Step-by-Step Instructions

Follow these steps carefully

1

Locate the airbox

Open the hood on the B8.5 A5. The engine air filter box is on the passenger side of the engine bay. It is a large black plastic housing with an intake duct.

2

Open the airbox lid

Release the metal clips around the airbox lid. On the B8.5 there are typically 4-6 clips. Lift the lid carefully without forcing it.

3

Remove the old filter

Lift out the old filter and note which way it faces. The filter has a rubber seal that must orient correctly. Compare old and new for size.

4

Install the new filter

Wipe the inside of the airbox with a damp cloth. Place the new filter in the same orientation. Ensure the seal sits flat.

5

Close up and verify

Close the lid and secure all clips. Verify the intake duct is connected. Start the engine and confirm smooth idle.

6

Test drive

Take a short drive to confirm normal power. A clean filter restores throttle response on the turbo engine.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Forcing the airbox clips - the B8.5 clips are plastic and snap.
  • • Installing the filter upside down - note the old orientation.
  • • Leaving the intake hose disconnected - it triggers a check-engine light.
  • • Using a filter that does not match the 1.8/2.0 TFSI airbox.
