Not for sure, but I would think that the 07 stuff will fit it.

I just got 08 F250 SD 5.4, I call or E-mail the manufacturer of the aftermarket part to make sure things are the same as 07 most of them are helpful

i thought the 07 stuff would fit too but apparently it doesn't. i had a local place call and try to dig up some stuff, all the manufacturers they called said no on the 07 parts...something must be different or they haven't tried fitting the older stuff up yet. hopefully something will turn up soon.

what kind of gas mileage are the 08 5.4 guys getting???? i have 3.73's with 600 miles on the clock, im getting 12 city and 16 highway.

It might be more about emissions than anything else. 2008 emissions changed a lot, especially for the green states (CA, NY, MA, ME, VT).

They may not have gotten CARB certified yet for 2008 vehicles.

I agree I bet they either haven't tried to see if it works or are having trouble with emissions. I am a bit out of the loop on the 3V's but I don't think anything has changed significantly on them yet.

Seems about right. Have a 08 with 5.4L / 3.73 and get less mpg, though have many mountains to overcome all the time. So far very reliable and manhandles my 18ft enclosed trailer over the mountains.
