LS Classic Series Gen III Breather Valley Plates combine the classic look and function of an OEM style chrome oil fill tube and breather cap into a modern LS engine. Precision CNC-machined from 1/4” billet aluminum, the plates replace the stock cast aluminum 10 bolt valley pans on Gen III LS engines. The valley plates have a black powder coat finish and include all of the necessary O-rings, seals, and stainless steel fasteners. Breather valley plates have NO provision for oil filling.
