Hi guys,
given that the AT rad' for the N54 loses approximately 12% of its frontal surface area for the purposes of transmission cooling, the Tech' at PWR recommended the use of their "Close Mesh Core Configuration", for vehicles that are not daily driven or for owners that live in a cooler climate.
The core upgrade adds an additional $165 to the cost of the rad', however I am told that pricing can be reduced as part of the GB, pending the total number of units ordered.
FYI,
the MT 5970 rad' can also be ordered with the core upgrade, for those guys wishing to maximise cooling efficiency at the race track.
Here are two cross-sectional pics illustrating the difference in core construction between the standard core and the "Close Mesh" option on the right.
Cheers,
Justin.
