Mobile 1 full synthetic for the trans(did it for my wifes ZX2 at 75K and it was night and day) for the engine oil if you have 90K on mineral based oil, I would just stick to quality Dino oils(Valvoline Maxlife comes to mind) and a NAPA Gold(Wix) filter. I run M1 EP and NAPA Gold in mine, but I switched to full syn oil at 21K. Also if its in your budget an external tranny cooler is a good idea.
for the wires try these
clicky
