I have the BD intercooler, and I gotta say, I went with it over the banks because of the extruded fin design and the overall bar design, those two things seem superior in my eyes to the banks. The fit and finish of the BD unit is top notch, there is even a slight bend in the intercooler to match the profile of the front of the truck, which I was not expecting and thought was pretty trick. The end tanks are cast and the elbows have a nice transition for good air flow, I have only had 42psi going through it being pushed by a 4094 avant, but my egt's are lower than they were on the same tuning (essentially) as the stock turbo, and I haven't noticed any lag due to the intercooler, turbo still spools quick even though it's bigger.
