LS Gen III Billet Valley Pan Cover Plate Knock Sensor Delete for LS6 LS1 Gen 3

Product Overview

This aftermarket replacement valley pan cover plate is designed for LS Gen III engine applications and covers the valley area when the knock sensors have been removed or relocated. The billet-style plate fits LS6 and LS1 Gen 3 engine families and serves as a block-off cover for the lifter valley opening. A valley pan cover plate seals the top of the engine block between the cylinder heads, keeping oil contained and debris out of the lifter valley. The knock sensor delete feature means the plate mounts in place of the factory knock sensor provision, which is common when the sensors have been relocated to the side of the block.
