Fitment Notes

• This oil pan is designed for K-series engine swap applications only - it is NOT a direct-fit pan for vehicles that came with a K-series engine from the factory.
• Does NOT fit the DC5 Acura RSX, CL9 Acura TSX, or EP3 Honda Civic Si - these vehicles require a different K-series pan as the subframe geometry conflicts with this pan's sump profile.
• Requires the Acura RSX oil pump assembly (OEM Part #15100-PRB-A01, sold separately) - the stock K-series oil pump from other applications may require slight notching to clear certain K-series main caps.
• Requires the Acura RSX windage tray (OEM Part #11211-PNC-000, sold separately) for proper oil control and crankshaft clearance.
• Oil pump assembly may require slight notching to clear certain K-series main caps - verify clearance during mock-up before final installation.
• Gasket and mounting hardware included. A windage tray is required but sold separately.
• For engine swaps: verify chassis-specific dimensions and subframe clearance before ordering - sump dimensions are 5.5" deep, 16.75" long, 9" wide.

Features

• Race-proven trap door assembly and anti-slosh baffle system keep oil contained at the oil pump pickup during hard cornering, braking, and acceleration - preventing oil starvation under sustained lateral and longitudinal G-loads.
• 6.5 quart capacity - approximately 2 quarts more than stock - provides additional oil volume for improved thermal buffering and lubrication reserve during extended high-RPM operation.
• 5.5-inch deep sump with dimensions of 16.75" long x 9" wide provides maximum oil volume within the packaging constraints of most Honda/Acura K-swap chassis.
• Thick steel pan rail provides a rigid, flat mating surface for leak-free sealing against the K-series engine block - a critical feature for track applications where oil pan gasket failure is a reliability concern.
• Dual 1/2" NPT bungs pre-installed for turbo/supercharger oil drain return line and oil temperature sensor - eliminates custom fabrication on forced induction K-swap builds.
• Magnetic drain plug captures ferrous metallic debris during oil changes to provide early warning of internal engine wear.
• Fully fabricated from high-quality steel and hand-welded at Moroso's facility in Guilford, Connecticut.
• Black powdercoated finish for superior corrosion resistance and long-term durability.

Product Description

The Moroso 20915 is a road race baffled steel oil pan purpose-built for Honda K20 and K24 engine swaps into classic Honda and Acura chassis. It is not a factory-fit replacement - it is engineered specifically for K-series engines installed into older platforms including the EF, EG, EK, and ES Civic, DA and DC Integra, CB and CD Accord, BB Prelude, and GD Fit. The K-swap community has long recognized this pan as one of the most capable oil control solutions available for these builds, combining an expanded 6.5-quart capacity with a race-proven trap door and anti-slosh baffle assembly that keeps oil available to the pickup regardless of G-force direction or duration.

The sump dimensions - 5.5 inches deep, 16.75 inches long, and 9 inches wide - provide maximum oil volume within the packaging constraints of most Honda/Acura K-swap chassis, while the thick steel pan rail delivers the rigid, flat mating surface necessary for a leak-free seal against the K-series block. Two pre-installed 1/2" NPT bungs accommodate turbo or supercharger oil drain return lines and oil temperature senders - a practical inclusion for the majority of K-swap builds running forced induction. This pan requires the Acura RSX oil pump assembly (OEM #15100-PRB-A01) and RSX windage tray (OEM #11211-PNC-000), both sold separately. Note that the oil pump assembly may require slight notching to clear certain K-series main caps on some builds.

One important exclusion: the 20915 does not fit the DC5 Acura RSX, CL9 Acura TSX, or EP3 Honda Civic Si - the subframe geometry on these chassis conflicts with this pan's sump profile. Builders working with those chassis require a different K-series oil pan. For all covered swap chassis, the Moroso 20915 is hand-fabricated from steel and finished in Moroso's in-house black powdercoat operation in Guilford, Connecticut, and is backed by Moroso's standard warranty for their oil pan product line.
