Installed mine last night. I have AWE S3 TOP (no coupler) and the IC hose was a tight fit to get over but I managed to shoe horn it on. The clamp rings that come with the hoses wouldn't fit so I had to use a larger Tbolt for now. The cold side hoses fit much easier. I have BSH meth throttle body pipe and the hose slid right over.
I am a little slower than the instructions said. About 4 hrs total. That includes about 30-40 mins of trying to shoe horn the hose over TOP pipe. Also had to search out a few tools and make tools work for other purposes. Overall not to bad, just lay out the tools before hand and its an easy 3 hrs tops. Also if you have stock Pipes, and still use coupler on TOP, things should go even faster.
NOTE: Don't forget to move the temp sensor which is the last step. Its on the bumper and can be easily be moved before installing the bumper back on. Instructions don't really say what to do with the radiator air fin pieces. I cut mine to fit the top of the grill still.
My previous setup was S3 ic, AWE hoses.
Driving impression
So far I have only limited driving about 60 miles. In traffic there is still heat soak I can watch my IATs climb. Main difference I notice is that the IATs drop like crazy even in the smallest sprint. In normal freeway driving the IATs stay about 10F above ambient, it was about 80 today on way to work. In traffic about 30F more. And getting on the car seems to pull harder. I also feel like it is less laggy than before when jumping on throttle.
