CSF BMW B58/B48 Front Mount Triple-Pass Heat Exchanger w/Rock GuardThe 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.

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.This Part Fits:

Decent value for the money.
Size: 6FT*6FT, Color: Grey
Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.

Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart.
Itβs not made of quality material and is very flimsy. The only reason Iβm not returning it is because itβs too difficult to put together and I donβt wanna spend that much time trying to take it apart. Do not buy this!

Cheap
Size: 6FT*6FT, Color: Black
They serve their purpose as long as you leve them in one place and not moving them around and they're kinda flimsy and some of the velcros are cut too short and can't stay closed
