Okay, I changed my comment to SOME cars. What I saw on my car was that the benefit gets lost when the temperature gets above 30 Celsius and gets significantly worse at 50 C. It is never much better anyway, except when lifting the intake temp above the 2C / 35F barrier. Strangely that seems to be a FE cliff on the Insight.
But not all engines are the same and EGRs will differ too.
