Default Way to cool the intake temps?

Is there a reasonable way to cool the intake temps? Slow moving I am seeing intake temps over 140f. I would like to get them back to ambient. Any suggestions?

Bags of ice?
Just kidding. Make sure you don't have an intake leak before the Maf. Make sure your airbox is sealed up nice and tight. If it was after the maf, you'd throw codes.

Cold air intake? Water injection? Drive through more ponds and rivers/creeks?

The IAT is basically measuring the air under the hood, where opening from air intake is. One way to make it cooler would be duct from outside, insulated. ECU will adapt, it is not like an extra 76 HP, etc.

There is some "race" insulate material that you normally see in most engine bays of race cars. This is the gold/silver wrap material. You can try ordering some of that and wrapping it around your intake pipe and box. Also, perhaps changing out the intake filter with a free flowing element. I'm not a big fan of the aluminum cold air intakes as they get heat soaked just as bad, if not more than stock.

I use a dual nozzle water:meth injection in my other car (track use) along with thermo wrapped carbon air box. But I am trying to keep it simple on the rover. Air box is sealed and in good condition. A new oem filter was recently installed. Guess there aren't alot of options.

It is sucking in hot air, if you really want lower temps you need to change where it gets its air from.
If you notice the air intake trumpet is right behind the radiator.

Some other brands of vehicles extend that snout to the front wall behind the grille. Might make more difference on a turbo vehicle at Autobahn speeds, but Mom's taxi service - not so much. Back in the late 60's we called 'em vacuum cleaners (early ram air).
