Yeah I plan on ducting mine since I only have a 6 by 12" hole in the bottom. It is probably the #1 thing you can do to lower coolant temps again if you are doing a grill block, more than running the fans more or anything.

Plus it just makes the "system" (car) MUCH more efficient. Oh, one more thing that I have noticed (with a grill block and will probably notice it more with the ducting) is how clean my engine bay has been... it looks pretty much BRAND NEW.
