Hi Guys, Been lurking for a week or so, but just registered to add that Pipercross tell me today that they can make a panel filter for a Mk 2 172. I have ordered one for delivery in 10 days or so, so when it comes I will repost & confirm that it does indeed fit (or not), with part number etc. Im enjoying my 172 (after 3 Scoobys in a row - which are so capable they get boring after a bit - even when youre as old as me)
