Hey ALL,
Got to looking for my oil leak today and noticed that there's no AIH on the inlets! (was going to perform the AIH removal MOD since she is deadlined)
From your guys' perspective, does this look stock? Has the plenum been exchanged? Or am I just missing the AIH? Maybe i've had too many beers already. WAIT, what the hell am I saying???
Appreciate the help!

Looks to me like you have a Early 99 truck... Not a 99.5


Get a better shot on the intake plentums or the compressor housing and I can tell for sure.

LOL...manufacture date of 11/98! You are correct sir! Didn't realize there was a difference for the AIH?:wedgie

That is the ONE sure fire way to quickly tell a early 99 from a later... If it has a IAH, its a late... if not... nope.
