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. A 90-degree banjo bolt (AF77-5017) can be purchased separately and bolted to the top of the valley plate for installing the M16 x 1.5mm oil pressure sensor on an angle for better clearance.
