Wow bet you didn't think I'd get all this when u first posted!!
I may not know that much when it comes tO the dmax but heat x change and airflow I know.
The dmax exchanges heat between almost all fluids and intake air many times over 2 fluid to fluid x xchanges and multiple air to fluid heat exchanges and 1 air to air exchange in the stack and in the stack everything it goes thru the air gets hotter and hotter so there is less heat removed.
Basically with all the heat exchanges if u remove extra heat from a add on air to fluid heat exchanger anywhere outside the stack it will help cool most everything. How much and how efficiently is a whole another big long debate. This may have been covered but I couldn't read all the fighting.
Insulating the intake ducting is even less then a dent in the pond though.
Clean the stack, check for boost leaks, check ur balance rates, have someone double check your tunes ( turbo vane position while towing could cause this), keep the rpms above 1900 while towing and keep your a/c off and recheck your results. A oil temp sensor or gauge is a great idea for someone that tows heavy and hot once u overheat oil pass the temp it breakdown at the oil is junk which can ruin a motor.
I'm not even gonna go into how hot is to hot only way to truly find out is to contact the oil MFG.
It sucks when u buy a supper expensive powerhouse truck like a d max and then tow heavy with it and have to turn off the a/c to keep it cool but it does help.
P.s. Double check the glycol level of your coolant too the higher the level the less efficiently it x changes heat.
