I talked to www.greenfilterusa.com and they said that they don't have the kit available yet for our Crossfires and it's only the twister filters with aluminum casing that they're selling right now. He suggested that we can install it ourselves.

My question is what's the size and length of tubes do we need to get? I didn't really see any difficulty in replacing the plastic tubes with an aluminum one and securing it with silicon.

Any shots out there?
