Not certain how you determine "best." Today's opinions will resemble last years opinions which are similar to opinions offered 7 years ago.

There is no best especially if it's a stock car or near stock. Just follow the owners manual and you can't go wrong

Get NGK plugs like the car came with. Get a synthetic gear lube like Royal Purple, Redline, etc. for trans and diff. Simple as that.

Check the links in this thread... https://my350z.com/forum/maintenance...intenance.html ... to the trans and diff change DIYs. Lots of suggestions on fluids, mixs, etc.
