They replace most of the turbo - intercooler - throttle body hoses. They are less likely to collapse under pressure and look nice too. Also your old hoses may be starting to split etc so it's more of a piece of mind mod rather than getting extra horses directly from replacing them

I don't think there is a replacement for the rigid pipe to pancake pipe included in the kit though is there? Notieced this when changing the turbo yesterday.?
Shall we count you in then!?
