    For wires AC Delcos are fine or PrJ or Taylor wires really whichever you prefer there not going to add any power difference.

    Yup those are it. Advance usually Carries them in stock so you don't have to order them.

    AL605's, gap them at .050".

    You can get either the lifetime warranty wires, or get MSD 8.5mm or PRJ 10.4mm wires.

    Performance gain isn't probably anything over the standard 7mm factory sized wires, you just get to dress up the engine bay a bit.
