Choose your engine size

The 2013 Audi TT uses different engine air filter part numbers by engine. Select your engine, then use the part numbers in that panel.

Not sure which engine you have?

Check the sticker on the driver's door jamb (open the door and look at the door frame) — it lists the engine displacement. You can also look at the rear of the car: a V6 badge means the larger engine; no engine badge typically indicates the base 4-cylinder (I4). When in doubt, check your owner's manual or the underhood emissions sticker.
