Thanks and this helps. I'm just not sure if the top/back piece is part of the normal design or is part of the blockage design. I'll try and grab a picture of the pieces.

I went ahead and removed the front top shield figuring if I have any issues I have the TBS to fall back on. I left the rear top shield in place.

Gonna be hard to get full efficiency with the newer CAC's since Ford changed them internally.

I said screw it and got the Wagner.

This the 2013+ CAC have what appear to be foam pieces internally that prevent efficiency. It basically looks like they attempted to do everything possible to raise the temps in the CAC in a hope to vaporize the condensate, IMHO.

I pulled the top plate and mine and in about 200 miles had the limp mose issue in the rain. Threw that sucker right back on and have had no issues since.

All I know WBY5 box code that they flashed me to SUCKS royally.

You just remove the top front piece only.

I removed it all. I want air to flow through it, not through then deflected downwards then somewhere else.

I will not get the flash until I see what it does for the truck. I don't want to lose any power. Of course since I am tuned anyway it makes no difference.

Hopefully someone can report how the new flash works.

Get a sct tuner and a tune for the truck I your concerned about it. IMO that's the best way to go. You can get a safe 87oct tune if you don't care about performance at all vs a performance tune. Sure it's a few hundred bucks but it's a better/long term fix vs Fords band-aid fix.

Fair point I think but for a tuner noob like myself how would a 87oct tune here directly improve this issue? I know we've been talking about the PCM update possibly changing the tune to help, or assuming, but I've never hear folks say a sct tune or other is the way to go to have this issue fixed. Does the SCT tune by default adjust things to correct this issue?

Again this isn't challenging at all. I know very little about tunes and never done one and likely wouldn't. I can't pay to play.
