good info - but no pressure drop data.

Stock- aluminum core with crimped on plastic tanks; O-ring seals with plastic pipes
STETT- double welded all aluminum; 4 ply double layer silicone connectors with 304 stainless steel pipes
Stock- 425 cubic inches
STETT- 600 cubic inches (41% more)
AMBIENT SURFACE AREA:
Stock- 100 sq in
STETT- 200 sq in (100% more) -- Taller (more ambient air exposure and easy penetration- quicker cooling) rather than deeper/thicker which requires more air at a higher velocity to fully penetrate and provide the thermal energy conversion.
Where the stock cooler barely supports stock boost and horsepower levels, our cooler flows over 920cfm and will support over 620hp (80% capacity). Inlet temps are within 10-20 degrees over ambient at 80% capacity or less. Power gains are going to vary depending on your modifications. We don't advertise HP gains because they do GREATLY depend on your modifications and rather than being misleading we feel that the proven design we have and it's specifications sell itself (as it should when purchasing an intercooler). Those running more boost (and more HP) should see more gains and will sustain those gains much more efficiently than the stock cooler.
Installation is not extremely difficult but is probably not ideal for someone looking for their first car mod project. But, this is also a FMIC for the serious modders because it CAN handle and make power above where many other units can't. It does require modification of the plastic shroud behind the bumper but any FMIC like this will require the same (thanks BMW for leaving us no room ). The BMW clamps on the factory intercooler piping are non adjustable and seamless. So it does require cutting these clamps off. Again, any intercooler upgrade that replaces the weak and flimsy stock piping will require this. There are no big, bulky brackets just TWO simple bolts, utilizing existing bolt holes in the car's frame rails. Each kit comes with the cooler, the stainless piping and clamps, the heavy duty 4 ply double layer silicone hoses and the two attaching bolts.
