make sure to change your ext filter after a few thousand after 1st change.
it not like it's gonna free up more hp.
just be more efficient at putting the hp to the wheels.
get synth in the diffs too.
though the front'll need some sliplock for the lsd.
otherwise it chatters in turns.

Replace the ext filter with another Subaru one, or is there an alternative? Part #'s?

Could you expand on the sliplock at bit? How much of each fluid in the front diff and #'s for both the sliplock and what oil you put in there? Sorry for the dumb questions, but I've never even touched the front diff or sure how to fill it, but I'd like to start doing more of this stuff.
