The Moroso B-Series Baffled Steel Oil Pan Kit (20001) is a high-performance wet sump oil pan designed for Honda and Acura B-Series engines. Engineered to improve oil control, maintain consistent lubrication, and provide dependable performance under demanding driving conditions, this stock-depth oil pan is an excellent upgrade for street performance, drag racing, road racing, and forced-induction applications.

Manufactured from durable steel with a protective black finish, the Moroso 20001 features an integrated oil control baffle designed to help keep engine oil surrounding the factory oil pump pickup during aggressive acceleration, braking, and cornering. This improved oil management helps reduce the risk of oil starvation associated with excessive oil movement inside the crankcase.

Unlike basic factory-style replacement oil pans, the Moroso 20001 incorporates performance-oriented features, including a fully surrounding pickup baffle, a 1/2-inch NPT turbocharger oil drain provision, and an additional port for oil temperature monitoring. These features make it particularly useful for enthusiasts building turbocharged or supercharged B-Series engines.

Designed with a stock-depth sump, this oil pan maintains factory-style ground clearance and is compatible with the original oil pump and pickup assembly. The included gasket and mounting hardware provide the necessary components for installation.

Whether replacing a damaged factory oil pan or upgrading a high-performance B16, B18, or B20 engine, the Moroso 20001 delivers improved oil management, durable construction, and the reliability expected from Moroso performance products.
