Many have requested part number so I thought I would start new thread.
I complained of drivers side a-pillar wind noise to my dealer and they installed a much thicker piece of weather stripping on the door frame that seems to have solved problem.

My ticket says:
QTY (1)

FP-Number: YC3Z-25025K11-AA

Description: Insulator

That's all I have on the ticket.

 

Does it go all the way around the door? A full replacement?

 

Looks like K10 is the passenger side...

 

It runs from the dash cowling up to the top rear corner of the door. It doesn't go all the way around the perimeter that I can tell. It's a much different looking piece than the original.

I compared it to a friend of mine that has a newer Job 2 F350 and his is the same as my original piece.

 

Sorry-it looks like I don't know what the insulator looks like.
I still am getting some whistling--I am headed to the dealer and will let you know what happens.

I now think it is a small triangle piece about half way up the front of the front door mounted on the door frame.

 

Yep. Forgot to post this when I looked it up originally. 25K10 is same part on the other door.

 

Mine has a wind noise on the passenger side. If I turn the air off the noise goes away. Did you ever notice if your noise went away if the air wasn't on?

 

Mine is unrelated to the HVAC system. It comes from the a-pillar area.

 

If you do Epic's door mod seal all that noise will go away!

 

negative.... I did epics mod and it did not take away my noise. I am assuming that there are a couple of issues that is causing the noise.

 

Thanks for posting the PN…reps sent

 

got the same thing since brand new last week...driving me nuts...
