Well, as far as the engine oil goes, I have a perrin CAI and you'll probably be surprised when I say the color of oil changes to dark/black very soon. I do not have any data with regard to an actual oil sample analysis from a testing agency for comparison between oil condition with stock intake and the perrin CAI. But with about ~3000miles of absolutely no track/off-road use on fully synthetic oil (as recomended by the factory) I have noticed the oil going dark/black.

Now, there might be other factors involved due to which this might be happening but I just like to be safe than sorry
Tranny/diff fluids can probably wait but who cares once the car is on jack stands, might as well go on and complete the full circle

Also, were you on mnsubaru?
