Rad and fan combo

A hot day in Canada?
If I had a real Formula S and was dead set on an aluminum radiator I'd go with a Cold-case and paint it black.
One of the vendors here. Don't be fooled by the old 3row 4row BS. Dual 1" to 1-1/4" tubes are better.
There are also alum rads on eBay that have an optional black finish.
