Not sure if this is what you are looking for or if they are available in EU, but I have this on my 2017 A5 Cab Kohlefaser Luft-Technik Intake System, You will definitely hear intake noise! There is also much more noticeable turbo noise. This removes the entire stock airbox, uses the original air duct between the hood and grill then straight to the area of the air filter. Also replaces the air duct between the filter and the turbo inlet giving you the increased intake/turbo noise.Thanks for the replies guys.
Can anyone suggest a cone air filter with a short ram intake for my A5? Or is that not a thing for the A5?
Also will the panel air filter make any difference to the sound - anyone there who has done this and can comment?
I have the K&N drop in filter on the 2016 A5 Coupe, not really any appreciable intake noise from it. Mainly purchased for the reusability.
