This GM LS valley plate banjo adapter is designed to fit factory or Aftermarket valley plates including the Aeroflow Performance valley plates. It is designed to fit the factory oil pressure switch with a M16 x 1.50mm thread. The stainless-steel banjo and adapter allow you to swivel the oil pressure switch in various positions to clear intake manifolds and accessories. This low-profile banjo (27mm Total Height) will sit the oil pressure switch horizontally rather than the factory position (vertically) to allow for greater clearance.
