Mind if I ask what you installed it on?
- It was on a MK 7 GTI without the front assist. I have no idea how it would fit on a wagon.
- The hoses fit fine, except for the stock radiator where you need the smaller one to fill in the gap.
- I did spray some hairspray in the hoses to make them easier to slide on, then once it dries it acts like a weak adhesive
- The only clamps that I had to replace were the two larger ones for the stock IC. The other four were fine
- If you have a secondary air injection pump will have to bend the bracket that holds the electrical connector so that the hose doesn't fit, but that's easy enough to do.
- I did the installation by myself and used a jack to hold the IC up to mark the holes and I was able to get it just about perfectly level.
