A - so cars cant accurately measure their own intake at a standstill? Yes you are right especially with heat soaked MAF's!

B - the infared temp sensor was to show the differences in temperatures of the underhood components versus the front intake snorkel.

C - your right - true intake temps have not changed - they are pretty much the same as ambient air temps yet the heat soaked MAF tells the car that much hotter air is entering the engine.....Ill post some readings from driving back to back tonight.

no one is trying to lower the air temps. just measure it more accurately independent of the under hood temperatures of the engine approaching 200f!!!
