Acura 1.8L Aluminum Oil Pan

The Acura 1.8L Aluminum Oil Pan by MOROSO is purpose-built for street and strip applications where engine cooling and weight reduction matter. This driver-side sump design delivers the efficiency and durability that serious engine builders and performance mechanics demand, whether you're tuning a daily driver or preparing a competition-ready platform. The 5-quart capacity strikes a practical balance between adequate oil volume and compact packaging—critical for engine bay layouts that prioritize clearance and airflow around turbochargers or supercharger components.

Manufactured from lightweight aluminum, this oil pan reduces unsprung weight and lowers the vehicle's center of gravity compared to cast-iron alternatives—a measurable advantage in handling response and brake performance. The 5.625-inch depth provides ample ground clearance for aggressive suspension setups and low-ride-height builds without sacrificing oil capacity. The integrated 1/2-inch NPT drainback port enables seamless integration with external oil coolers, catch cans, or standalone cooling systems, allowing you to dial in engine operating temperatures precisely. This design accommodates B-Series engine architecture, making it a direct bolt-in for Honda/Acura platforms that demand OE fitment quality with aftermarket durability.

Street and strip enthusiasts, engine builders, and tuners gravitate toward this pan because it handles both daily commuting and track duty without compromise. The aluminum construction resists corrosion and thermal stress better than weaker cast designs, making it ideal for turbocharged or supercharged applications where sustained heat cycles are routine. Installation is straightforward for anyone with basic mechanical aptitude—the driver-side sump orientation and standard fastening points align with factory mounting locations, minimizing fabrication. Verify fitment with your specific B-Series engine variant and cooling system plumbing before ordering.
