Ferrea F1846P is a Competition Plus exhaust valve for the Nissan VG30ET, made from Ferrea's Super Alloy high temperature material for the heat a turbocharged exhaust port puts through a valve. The head measures 36.1 mm, the stem 8 mm and the overall length 124.5 mm, with a +1 mm oversize head over the stock valve for more exhaust port area. The same valve dimensions carry across to the SOHC RB30 family. Ferrea supplies this part number as a set of six, one for each exhaust port on the V6.
