Quick Question - Just wondered if any had replaced the air filter element on their 172 for a K&N, Green, piper X
Has it made any difference in terms of responsivness of the engine or noise/tone
Basically just wondering if its worth spending the 40 - 50 quid or not.
I understand that a viper/etc full enclosed induction kit would probably be better but I am not willing to spend that kind of money.
Thanx
