10 Row Oil Cooler Narrow Style

The 10 Row Oil Cooler Narrow Style from EARLS is purpose-built for serious engine builders and performance enthusiasts who demand reliable thermal management without compromising engine bay space. Whether you're running a high-output street engine, a track-focused build, or a turbocharged application, oil temperature control is critical to engine longevity and consistent performance. This narrow-profile design solves a common problem: fitting adequate cooling capacity into tight installation areas where standard coolers simply won't fit.

EARLS engineered this cooler with ten aluminum rows to maximize heat dissipation while maintaining a compact footprint measuring 11.8 x 2.5 x 11.9 inches. The narrow profile—measuring just 2.5 inches in width—allows installation in engine bays where lateral space is at a premium, such as modified Subarus, Hondas, or chassis with tight driver-side mounting constraints. The lightweight aluminum construction at 1.45 lbs minimizes unsprung mass and heat soak while the multi-row core design ensures effective oil-to-ambient heat transfer even at highway speeds, keeping oil viscosity stable and protecting critical engine components from thermal stress.

This cooler is ideal for turbocharged engines, supercharged applications, and naturally aspirated builds operating above stock parameters where elevated oil temperatures become a reliability concern. Installation typically requires AN-line routing from the engine oil filter adapter or pressure take-off to the cooler inlet, with return lines flowing back to the pan or sump. The compact narrow design makes it especially popular in modified street cars, road racing platforms, and engine swaps where traditional equipment placement proves impossible. Always pair with quality thermostatic sandwich adapters and proper line sizing to achieve optimal thermal control and protect your investment.
