Comptech's aftercooler radiator isn't as big as the Spearo. Infact, it looks like the heatercore out of a truck.

I bought a heater core of a 6.5 Chevy Diesel and fabbed it up. It looks just like the Comptech, lol.

Hmm... $35.00 vs. $400.00+

 

bought the used one off GoKart3 today. good luck to the rest of you guys with getting a hold of them!
