    “70 cooling tubes vs 55”.. I presume increased contact area for heat exchange.

    I don’t know that this is better or worse.

    My thoughts as well. I feel like cooling isn't the problem. Failing and breaking mixing coolant with oil is the problem.

    That is OEM, Ferrari changed the design a few years back. I've heard mixed reviews

    Is the original one not "full copper construction"? AW might know more about what makes it an upgrade.

    I am surprised that a more simple-to-make one isn't a thing. How about one with 5 larger tubes in it?...or three? Flow restrict, if needed, with some inserts?

    Fewer tubes would mean less surface area and less heat transfer.

    The tradeoff in minutes to achieve full temps would be?

    If you go from 55 to 5 pipes with equal total cross section area, it will take approximately 3.3 times as long (using conservative assumptions).

    There is incorrect information about the Genuine Ferrari version of it his item being posted above.

    The Ferrari 180846 has 61 tubes, arranged in concentric circles: 24 tubes, 18 tubes, 12 tubes, 6 tubes, 1 tube.
