Very little info on that web site, and sitting on top of the tunnel, how does that help the cooling, unless you tap into the coolers somehow? Or is it just a big heatsink of sorts? Also looks like you lose any space for a tunnel bag or spare fuel rack...
They help but they aren't magic... depending on where you ride to get to the good stuff, and what time of year you ride. I thought standard scratchers work just as good if not better at kicking up ice or snow to cool, but maybe placement of the cable types helps. I understand the Axys sleds run cooler than Pro-ride too. Even a solid flap helps.
Standard RMK additional cooler is in the bulkhead, and IIRC you would have to pretty much tear everything down to the bulkhead to install it. If you really need a cooler, I would wait for MTNTK to get more back in stock or you can go with Van Amberg but I believe their solution requires some cutting and welding... and I think shipping costs are going to hit you pretty hard either way. Good luck!
