Only looks toss when you try and do it in 3 hours!
I took 8 nights to fit my HDi to my GT and it sits perfectly, it's not an easy task and its something where a few parts do need a lot of thinking about, mainly cutting the bumper.
A lot of the bumper can be left it, just people hack away at it, to try and make it fit in one go.
I made several templates of my Tom's up, before I actually cut the fibreglass, and this is the finished product..
With what you're saying about the filter, your inlet pipe will most certainly be in the way, but you'll probably be able to use the hose you have, and find somewhere else for it!
Good luck, it's a stunning cooler kit!
