19 Row Stack Plate Oil Cooler -10an

The DERALE 19 Row Stack Plate Oil Cooler with -10AN connections is a high-efficiency fluid cooling solution engineered for performance applications demanding reliable thermal management. This plate-type cooler features a compact yet effective 19-row core that maximizes heat rejection surface area while maintaining a manageable footprint suitable for custom engine bay layouts. The aluminum construction with black powder coat finish provides corrosion resistance and a professional appearance across both street and competition builds.

The -10AN female O-ring inlet and outlet connections accept standard AN hose fittings, while included -10AN male adapters ensure flexible integration with various system configurations. The stacked-plate design delivers superior heat transfer efficiency compared to tube-and-fin alternatives, particularly when protecting engine oil temperatures during sustained high-RPM operation or in thermally demanding environments. Weighing 3.41 lbs and measuring 8.05 x 2.25 x 18.65 inches, the cooler balances adequate cooling capacity with practical installation constraints in tight engine compartments. Universal fitment allows integration into custom builds, restorations, and high-performance street machines where OEM cooling proves insufficient.

This cooler serves builders and owners of modified engines—naturally aspirated and boosted—where oil temperature regulation directly impacts bearing longevity, hydraulic stability, and overall engine durability. Circle track racers, road course competitors, and turbocharged street car enthusiasts rely on efficient aftermarket coolers to maintain optimal fluid temperatures under continuous load. The plate-stack construction handles elevated flow rates without excessive pressure drop, making it suitable for systems running electric or mechanical pumps at varying volumes.

DERALE has established expertise in thermal management across automotive, marine, and industrial segments. The 19-row capacity sits between entry-level and heavy-duty cooling solutions, offering a practical upgrade path for builders seeking measurable temperature reduction without oversizing infrastructure or parasitic drag concerns associated with oversized coolers.
