Yes, it does.

You also might want to use some fuel injector cleaner it will also burn off some of the carbon build up in the valves/stem (Redline or Amsoil), spark plugs, air filter, oil chg., oil filter, and check your timming. Good luck!

I have not replaced one on a 280zx but I would assume it would be on the exhaust manifold. Also if you are going to replace it yourself save alot of time and buy a O2 wrench you'll need it.
