This topic might have been covered already but I would like an updated version of it. I recently have focused on buying cooling mods for my cobra knowing that cooling is a big thing for these cars and I wanted to start with my heat exchanger, ive seen people swap the stock one for a gt500 one and I wanted to do the same so I bought the crash bar necessary for the swap but I am just stuck on looking for the exchanger itself because when looking for it I see two types of brand which are PLM and AFCO the prices are big in my opinion one being at 595 and the AFCO at around 900 and also I see some with fans and with out so I wanted to know which one would be the best to buy for cooling?
