Hi!

I've got std intercoolers from a S1 and S2 in my garage. They look quite different and I don't know which one to fit? Which one is better? It looks like the S1 intercooler is bigger and more solid (metal casing instead of plastics).

 

If you have a S2 i'd fit the proper intercooler, there won't be much in it and at least it will all fit first time and properly.........
