Did a DIY breather extension for the diffs, tcase and transmission.
After buying an "onboard air kit" I learned my lesson that a) you won't half the fittings they give you b) you usually get crappy fittings like compression instead of push to connect, etc.
And doing it DIY, you can come up with a better routing method.
The terrafirma or ARB kit is literally just some hose and a few PTC fittings. On to Mcmaster...
That's everything you need. I had some 1/4" p-clips that I used to secure the tcase and trans line to the immobilizer switch.
The tcase and trans line go up the RH side, and go from 6mm to 8mm hose using reducer fittings. Then the 8mm line is routed behind the engine using a couple existing clips to snap into. The line meets up with the diff lines, merges into a single 8mm line, and goes up along the snorkel. Then stick the hose into the snorkel so no water gets in.
Had to put in new magnecor wires since one off my sti wires (#4) rusted out and was causing misfires and a P0304 code. Left the manifold on and did the entire job in less than three hours. A big improvement since the last time I did it I spent a day and a half. SAI tubing is a real PiTA! It's amazing how much better the rig feels with the new wires.
