RS6 Cold Air Intake Options

[nubcake]

It'll never flow enough to hit the limit with any kind of K04, really. Too many restrictions everywhere.
If you want to run 700+ chp (equivalent of maxing out MAFs), you need to redo the whole intake tract anyway.
My own car did throw the "MAF exceeded" DTC occasionally with TD04/K04 hybrids a few years back, but that was probably just a fluke.
