A few weeks back i got a scangauge 2 which displays the intake temperature(among other things), anyway i decided to do a test today. The intake temperature is normally about 2 degrees above the outside air temp as shown on the dash. I removed the oem air box and fitted a short ram cone filter; the intake temp rose on average by 15 degrees, 18 at one stage and by 30 degrees when idling.
There has been a fair bit of discussion about removing the air box for cone filters so at least this is definitive, it will drastically raise the intake temp.
