Hi bigfish, the intercooler itself is a piece of cake to install. The bonnet bit can be a bit fiddley, although I must admit the second time I was pretty cautious as I really didn't want to cock it twice. Really it all went together pretty well and sealed up pretty good. You can adjust the cooler up a bit if you need to, I didn't bother. When setting the position of your scoop I set the back of the scoop 12mm from the back of the bonnet. This was based on some golden advice from Bob I think it was at Fairline who makes the scoops for Cross Country.
