Without a big turbo I wouldn't bother. Here's why:
IOW, I just don't see the risk:reward benefit when running a stock turbo. You said you want to increase safety; sure, keeping the charge air temps cooler even after a long pull all the way up through the gears will help. But getting that benefit means increasing other risks from failure of the WMI system.
Unless you are tracking your car most weekends... But for a daily driver driven aggressively on the stock turbo, I wouldn't bother.
I'm sure you'll get opposing opinions!
All the best,

- With your Depo FMIC and snorkel, you are already keeping the charge air temps close to ambient in most cases.
- WMI introduces more potential boost leak locations.
- A failed check valve or solenoid could lead to engine hydro lock.
- Getting the intake valves hot cleans them reasonably well (although long-term WMI does better), but...
- No one has documented that (unlike some of the BMWs) gunk buildup on our valves causes noticeable performance degradation nor increased risk of LSPI or other potential bad things.
