Ferrari would use air to water intercooler. So the part that is being upgraded would be the part that doesn't see the free-stream air. This would be optimized to reject more heat from the limiting side - the air to water side for more horsepower.
Even if is a water intercooler, that water need to be cooled somewhere, I suspect in the sidepods, so while they might reduce the central section drag they might require bigger sidepods. This points to the central volume being more expensive drag wise vs sidepod volume which makes sense.
From my research, the intercooler falls under the ADUO development restrictions so if they update it they could update something else. It might look like a waste of the token to do only the intercooler.
But at the end of the day, special knock delaying fuel or not, as Venkyhere was saying, to get more power we need more oxigen in the ICE. And with the boost pressure limited to 4.8 bars by the regulation the only way to do that in a conventional way is to drop the intake temperature to make the charge air more dense.
Less conventional way to bring oxigen in the combustion chamber might be by having a oxigen rich fuel that brings with it some of the oxigen required for the burn. And maybe the higher temperature on the intake is used to evaporate more easily this oxigen before burning. But fuel flow limits mean you need to trade some hydrocarbons if you want oxigen.
Even less conventional would be to "separate" the air in its components such that you can "enrich" the intake air with oxigen, but for a F1 engine flow, volume, and weight requirements that would be sci-fi.
