   Underhood air temperatures have been shown to skyrocket on our trucks, often easily exceeding 180* and under severe tow conditions even exceed 240*.   This directly hurts us by pulling in that less dense hot air through the stock airbox opening. The problem is further compounded by making our turbo work harder to get the boost it desires. As a result the turbo still does get the boost the EMC is calling for because it is a dedicated hard worker, but the resulting output is ridiculously hot (as much as 500* swallow that!) since hot thin air in equals really hot air out after compression. Turbo efficiency just fell through the floor.
  Too bad for us that hot air isn't done yet, it heads directly over to the intercooler where it sends the intercooler temperature soaring. The intercooler is a hard worker just like the turbo, its job is to dump as much heat off the intake air charge that it can, and it excels at this task. Unfortunately the intercooler lives directly in front of the radiator, so it sheds heat and the radiator is left with less dense hot air to cool with. There goes radiator efficiency.
  Finally what the intercooler is not able to shed goes into the engine intake. Under these conditions we can still have 200* charge air temps, and aluminum is a lovely heat carrier so we add some heat load to the intake and heads before saying goodbye to this air for combustion. Thanks a lot hot intake air, you just added heat load that the coolant has to deal with directly from the intake and cylinder heads. Cooling system efficiency takes a hit.
"All this is great, but what can we do about it?"

    This particular problem is the easiest of all to deal with.   GM finally got smart and created a cold air intake for the 06 model. Fantastic for people just now buying a new truck, but it leaves the rest of us without what we need.   All of the Dmax trucks can benefit from true cold air intake, doesn't matter if it is an LB7 or an LLY and   it doesn't matter if they run hot or not.  The cold air intake is just a smart move period. Any intake system that actually takes in cool air instead of underhood air can correct the issues above.  Problem is that it seems they all are pricey (get a few hundred ready) and even worse most make no real attempt to get at the outside air. Fancy is great but results are what I care about.
  My airbox mod,  the TxC airbox mod or the TxC CAI, was invented to solve this part of the problem by eliminating the hot air in without eliminating too much cash out of your pocket while giving you the best results for the money.
   Just to be clear, I want everyone to know that the cold air intake is NOT a cure for the overheating problem, however it is what I consider to be the foundation that begins getting everything else in line where we want it to be.
