wires? GS' have individual coil packs, no need for wires.

also, think about:

water pump
all your fluids, not just transmission
not sure what else really...ask the dealership what normal maintenance would be for your situation. if not, i know that you can go to: www.luxurymotorworks.com and click on MAINTENANCE, then you can see what they would usually do.

as for spark plugs, i recently bought some NGK IX Iridium Plugs. going to have them installed for my dyno tuning / pulls tomorrow.

easier said than done, i am surprise you didn't say you were going to change cap and rotor too. are you doing this your self or are you taking it in some where?

I myself use Redline 75w-90. However, you can use many kinds. Might as well go with a synthetic since its only a few bucks more than regular fluid, and it protects better too.
