Not sure how much I'd believe from them. Their e46 M3 radiator claimed 32% increase in coolant surface area, 15% increase in air surface area, 25% increase in coolant capacity yet didn't make any difference to my coolant temps at all. It was a decent made product, and came in fancy packaging if I remember correctly, but didn't give any real world improvements at all.
I'm sure the new F10 charge coolers and oil cooler will be of reasonable quality, but can't see them yielding and huge benefits personally.
