Honestly, a couple degrees won't make much of a difference, but you want it to accurately read the temperature of the air going into the engine, not necessarily the temp of the outside air. The amount of air rushing over the sensor stabilizes what it will read (no worries on 'heat soak')... it just changes too slow for a forced induction application. On an NA bike, inlet air temp will never change drastically from the outside air temp in a short period of time.... unless you are letting it heat soak somehow (like, say, in drag racing where you get it hot and then sit in staging for 20 minutes with the bike off). For normal riding/circuit racing it's a non-issue.
Attack life... it's going to kill you anyway.
