VRSF does not have a divider plate on the hotside of the IC unless things have changed. The tabs on the rear of the VRSF are bent up, on this not bent.
BMS does have a hotside divider to direct air flow but has 2.5'' in and 3'' out. This appears to be 3'' in and out.
The listing says 7'' thick. Both the BMW and VRSF are listed as 7.5''.
So...who my guess is VRSF clone/knock off/ or the same product basically. VRSF maybe has USA distribution rights? These guys customized it by black anodization and the air flow piece for EU customers?
edit: the more I look at it the more it looks like a BMS clone. Who knows?
