Well the Airtec one I bought is really easy to fit. It uses the original mount for the standard IC and bolts through the little hole next to the near side headlight.
Unfortunately it wont fit if you have a standard IC and rad.
Mine came with silicone hose and all the fittings, not to bad for £70.00.
If you got for the pro-alloy one its a bit harder to fit, unless you have their front mount IC and it bolts straight to it! Even though I have the Prolloy IC I did however go for the Airtec as it's half the price......
