Proflow's LS valley covers are the latest accessories offered for the GM LS engine. These covers install between the two banks of cylinder heads, depending on your usage of knock sensors, displacement on demand, and active fuel management. The LS2/LS3 valley cover has provision to retain the factory oil pressure sensor fitting and a -06AN breather port to connect accessories such as oil catch cans. They are available in a black anodized or polished billet aluminium finish to match Proflow's popular valve covers and come with a composite gasket.
