Oil Pan Acura/Honda K-Series RR Baffled

The Oil Pan Acura/Honda K-Series RR Baffled by MOROSO (MPN 20921) is engineered for serious K-series engine builders and track enthusiasts who demand reliable oil containment under extreme acceleration, cornering, and sustained high-RPM operation. This baffled design directly addresses the critical failure point in stock and lightly modified K-series installations: oil starvation caused by fuel slosh during hard driving. Whether you're running a K20 or K24 in a street-driven RSX, Civic Si, or dedicated race car, proper oil management is non-negotiable for engine longevity.

MOROSO's baffled design incorporates internal dividers and trap doors that prevent oil from sloshing away from the pickup tube during lateral and vertical acceleration. This technology ensures consistent oil pressure delivery to the crankshaft, rod bearings, and cam bearings—components that fail catastrophically when starved of lubrication at 8,000+ RPM. The pan maintains OEM-compatible mounting points and clearance while adding approximately 8.9 lbs to your engine bay, making it a straightforward bolt-on upgrade requiring no custom fabrication or welding. The internal baffles are precisely engineered to maximize oil capacity while maintaining low-profile fitment in tight engine compartments typical of Honda and Acura chassis.

This pan is ideal for K-series swaps in compact platforms, track cars, autocross builds, and any application where sustained cornering forces or aggressive acceleration create dynamic oil movement. Installation is straightforward for anyone with basic mechanical skill—drain existing oil, unbolt the factory pan, install new gasket, and torque the MOROSO unit in place. Verify clearance between the pan and subframe or suspension components specific to your chassis configuration. This upgrade is particularly valuable for owners pushing beyond 350 horsepower or running extended track sessions where oil temperature and slosh dynamics become performance-limiting factors.
