Moroso 20912 Honda Prelude H Series Drag Racing Baffled Oil Pan

The Moroso 20912 oil pan is designed for Honda H-series 2.2L and 2.3L engines, making it a strong performance upgrade for Accord and Prelude applications, except 4WS models. Constructed from fully fabricated aluminum, this wet sump pan offers increased durability and reduced weight compared to stock designs. Its 5.5-quart capacity and compact 5-3/8-inch depth make it a practical choice for performance-oriented street and drag race builds.

To improve oil control under aggressive acceleration, Moroso built this pan with an integrated anti-slosh baffle and large trap door. These features help keep oil centered around the pickup, which is critical in high-performance conditions where oil movement can affect reliability. That makes this pan especially attractive for serious street cars, drag cars, and engine-swapped vehicles where consistent oil delivery matters.

This pan also includes extra provisions for custom performance setups, including 1/2-inch NPT ports for a turbo drain back and temperature sender. Moroso supplies a hardware kit with hex-drive studs and serrated-face flange nuts for installation. Because fitment can vary on swapped applications, builders are advised to check dimensions for proper clearance before installation.
