My car runs fine on the "7A" so I figured I wouldn't change it.
That's what the owners manual said when I looked it up online.
But as noted, the B is what showed at the NGK site making me think they had superseded the A, at least for NGK new production.
But have to agree those are some expensive plugs, guess because PZEV.
Checked my 3.0L V6, $10 spec NGK Irid plug, buy from AAP using code 30% off orders over $50, so knocks price down substantially.
