I have a 6.0 intercooler with plastic "tanks" on my OBS. Of course it's leaking now by the hot side tank/core joint. Did any of the 6.0s come with an OEM ALL aluminum version? I don't want to lay out $1200 for a "Mishy".
No, there are no factory 6.0 metal coolers. You could go with a 7.3 super duty aluminum cooler if you wanted. I don't think it would fit right in though.
