Product Description

The Moroso 20901 drag race baffled aluminum oil pan delivers superior oil control for Honda and Acura B-Series engines in street performance and drag racing applications. Fully fabricated from aluminum with a 1/4" thick pan rail, this oil pan features a kicked-out rear sump design that increases capacity to 5 quarts while improving oil control under hard acceleration. The dynamic trap door baffling system keeps oil directed to the pickup and prevents the crankshaft from contacting excess oil, allowing the engine to spin freely and achieve its full power potential. Two 1/2" NPT bungs are included for plumbing turbo oil return lines and installing an oil temperature sender, making this pan ideal for forced induction builds. The driver side sump location and 5-5/8" depth provide excellent ground clearance while maintaining compatibility with OEM exhaust manifolds and most aftermarket header combinations. A complete mounting kit with hex-drive studs and serrated-face flare nuts ensures secure installation, while the included magnetic drain plug captures metal particles. Uses the stock oil pan gasket and stock oil pump with pickup for straightforward installation. Whether you're building a weekend warrior or a dedicated drag car, the Moroso 20901 provides the oil control needed for consistent performance.
