Did I Miss The Launch? Is the IICE Cool On Sale?

As Carlo said, the boxer motor isn't operated at what you would call a rich mixture anywhere in the operational range. Eric is on the track too. Exhaust popping for the boxer and Motronic combination is caused by the mixture swinging too lean to combust. The unburned oxygen and fuel gets ignited with-a-pop during the next exhaust stroke.

And a slight adjustment to Eric's comment. The IICE Air richens up the mixture during leading throttle acceleration, and pays small dividends during transient throttle. The big increase to transient throttle enrichment is from the IICE Cool.

Did I miss the release and sale of the IICE Cool? Or is this a "tease"..
