Suit GM LS3 Series Engines with DOD delete.
Aeroflow Performance billet LS3 valley plate is perfect for those who want to clean up the look of their modern LS engine or create a custom touch.
Designed to be low profile that will eliminate any fitment issues with factory and aftermarket intakes ad still take the factory gasket. Precision manufactured from billet aluminium with a modern, race-inspired design and a cost-effective alternative to the factory GM pieces.
These valley plates are machined smooth on the underside, allowing for the elimination of Displacement-On-Demand (DOD) or Active Fuel Management (AFM), and instead feature O-Ring gaskets to seal them off. An extra 90-degree provision is bolted to the top of the valley plate for re-installing the oil pressure sensor if necessary.
