Long story short, I'm gonna make a RR purchase for Boots, AIH adapter, Misc. Stuff, etc. And Looking at the IC boots I can't tell or test whether I need 3"X3" or "3X3.25". And thanks to my DW's steller driving skills, My '02 is now the family driver for the foreseeable future. So I can't tear down anything until her ride comes back. So the question to anybody with a '02 / 250 is is there a standard ratio for that Boot or is it truly a Crap shoot?
Thanks,

 

I have an 02 f250, 7.3, extra cab, short bed. I just had my drivers side IC pipe off. The connection at the turbo is the same size on both ends. ( 3 X 3 ?) The connection at the IC is larger at the IC end.(3 X 3.25 ?) I went out and looked and the other side appears to be the same set up. I did notice that the boot at the intake has "cold side only" printed on it. Hope that helps.
