But I would be hesitant to block the radiator, even a little bit (like I would not even do the Big Mouth), especially with an S280 installed, yes, even with a Mountune/Pro Alloy/Mishi radiator.
I forgot, are you running the BA intercooler as well? (Since that also blocks a larger part of the radiator, than the smaller ICs.)
