K&N Replacement Air Filter - Audi B9 A4 / A5 / S5 / RS5 / Allroad
Seems like a cheesy upgrade in a stock air box…
However, after R&R from factory Audi paper filter, comfort powertrain setting felt like dynamic and dynamic felt like a faster car. Some reduction in engine braking, but it is a worthy trade-off. Side note; I run individual mode setup with comfort P/T and dynamic for all other parameters, makes for a better economy mode than comfort.
Good buy. I recommended to my Audi people.
