As of a couple months ago, the intake is available again. I thought it was a mistake on their website but I emailed them and they said that they are selling them again.

From what I remember, the 5.4L 3v was not an option in cast. I could only get it in billet. I'm not sure if you're looking to do a 5.4L 3v, but if it's now available, I would assume it was for the 4.6L 3v.Thats the cast version isnt it?
Have you called JPC? That would be the best/quickest way to get an answer.
