As you may know, I did this swap last week.
I can only go by mine being a CW and not a Wiffbitz one but I would imagine it should line up the same.
Have you taken your stock smic out? Or did you not have one as you need to transfer all the brackets over.
Here is a look from some different angles. I would say there is a degree of variability with positioning the brackets, i.e they can be slid around in different directions before tightening the m down causing them to seem "way out" if it's too high for the bracket to go over the bolt then loosten and slide the bracket down a bit and fine tune it. I was lucky and it went in first time, but believe me when I say I know it's fiddly getting it in there. A tip when getting it into the arch is cover the back with a cardboard cut out to protect the fins from getting bashed in your slowly building rage at trying to get it past the brake disk.
You will notice that there will be a gap between the ducting and your new intercooler. I had heard this was an issue and got some door draught excluder form B&Q although I would have liked to source something black and heavy duty, it is the right width for the job.
Hope some of that helps and any more questions let me know. (Took me hours and hours btw)
