intercooler & amsoil questions

[01excursion7.3]

I've never looked but did the 01 ex come with an intercooler?

I also want to switch to all amsoil synthetics. Front & rear end, t-case, tranny, and motor. I dunno what weights/kinds to get though, can anyone help me out? I'm in maine, and we have some cold winters.

I'm questioning if I want to do the intercooler, but I want to do the amsoil, tranny filter, and valve bodies (maybe john wood or that other guy). I also want to put in the 6.0 t cooler.

Then i'll get gauges & a chip.

Yes, All superdutys have a factory IC... and it does a good job for 90% of the trucks out there that are just a mild mod... Chip/intake/exhaust...

As far as the amsoil... what ever weight is there should go back... I run Dyno in everything but the tranny.
