The original OEM B58 heat exchanger is a 1-row unit that is 27mm thick. In comparison, CSF has used its industry-exclusive world's largest 2-row core (68mm) with CSF's B-Tube technology. A unique tank design allows the larger CSF core to still fit into the OEM cooling system housing. Another critical feature of the CSF BMW B58 high-performance heat exchanger is its unique triple-pass flow design. The water traveling through the upgraded heat exchanger flows through the radiator three times before exiting the cooler and flowing back into the manifold charge cooler. This ensures that the outlet water temperature of the heat exchanger is the absolute lowest it can be. The OEM design, as well as more expensive aftermarket designs, all have single-pass flow structures.

Great smell for the summer
Scent: Aquatic
Smells like a variety of citrus and a bit of the classic shower gel, really great scent for the summer and pairs well with colognes of citrus or fresh notes. Doesn't dry out skin and you'll still smell it for a good while on you after a couple of hours for me the scent last maybe 5-6 hours.

Nice refreshing seasonal body wash
Scent: Aquatic
Good fragrance body wash. I really do like cremos limited seasonal fragrances. This one is light and refreshing. Wish it would last a bit longer but overall does lather well and smells great while showering. A little goes a long way so I do appreciate that this bottle should last long. The viscosity of the liquid is easy to pour and suds up nicely with a loofah. Overall good value and would recommend.

Great smell and feel no cream after used .
Scent: Aquatic
I bought this for our son while he stays and visits our home, well he liked this so much he took it home. lol I guess he liked this more then the other scent of him s chemo at his house. He did say he liked the smell and it’s a good size bottle. Said he don’t have to put a lot of cologne on because this smells so good and he feels really clean.
