have you read the sheet from Scangauge that explains the abreviations?

that's the air temp at the MAS sensor.

In my Honda insight I usually shoot to run at 115 to 125 intake temp. yesterday I saw 154* on the intake temp, it scared me so I pulled off some of my grill block. the car still ran fine tho even at idle.

Dayum - I've been shooting for 150+ F. I usually see around 120 F during the day, and 105 F at night.

Straight from the manual "fia/cia- intake air temperature - temperature of the air going into the engine. At highway speed, this will typically be a few degrees higher than the outside temperature. At idle or low speed, it may reach higher than the outside temperature due to the low airflow onto the engine and the high under-good temperature warming up."

In my Q45 I found that to be accurate 100% of the time.
however, in my Kia Sportage, I have seen 140-150. And it has not been over 90 outside and I was driving 55 in the middle of the day.
Not sure what is happening there.
On the same day just moments later it dropped to 105.

WAIs have helped both my Dakota and my Magnum. The truck gained more dramatic increases in FE, though.

Lower air density means you can have higher effective compression to produce the same level of power. This means less fuel to do the same work with lower pumping losses. Broad statements about what is best will not cover specifics of individual vehicles. Some will work better and others will not. Best to experiment with your individual vehicle.

mine is usually 5-10'f higher than ambient temps when cruising and 10-15'f higher at idle. On all vehicles I have driven, specially my subaru, lower air intake temps give me better throttle response.
