Zetec Turbo Air filters
 

Looking at air filters for my ZT. Obviously the best option is a 60mm alloy outlet cone air filter to join straight onto the original turbo piping.

Just wondering what people are using? my options are pipercross, K&N, RamAir, ITG. At the moment i'm leaning towards the RamAir as it has a nice black finish option.
However, I've always been a bit cautious of Foam air filters as I've always wondered what happens if the foam breaks down? So has anyone had this happen? and what are you using?

Green all the way for me.

Foam are one of the most free flowing this side of steel mesh ones, but like you say I'd be a little concerned about them breaking down.
I've always ran Green filters on my cars, and wouldn't change to be honest.

Ring Green
