Cylinder heads are assembled or manufactured in different plants, so one bank may have NGK and the other Denso. Really no need for special spark plug sockets, replaced quite a few 2UZ ones while working at Lexus, only needed the special ones on FWD/AWD V6 engines where the intake manifold went over the rear head.
