CSF 2014+ BMW M3/M4 (F8X) Front Mount Heat Exchanger w/Rock Guard - BlackThe S55 power BMW F8X suffers heavily from heat soak. While the ideal solution is pairing the Front Mount Heat Exchanger with the Charge Air Cooler, you can still see significant improvements with just the Heat Exchanger. The ability for the system to remove as much heat as possible is the bigger of the two weak points in the system. So if you are planning to upgrade your S55 cooling system and can only start with one, the Heat Exchanger is the right

Best socks!

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
