Oil Cooler DLM -12AN 17.5in x 8.5in

The Oil Cooler DLM -12AN 17.5in x 8.5in by FLUIDYNE PERFORMANCE is a compact yet efficient thermal management solution engineered for serious automotive builders and track enthusiasts who demand consistent oil temperatures under extreme driving conditions. Whether you're running a high-horsepower street engine, a weekend track car, or a turbocharged build, oil temperature control is non-negotiable for longevity and performance reliability. This cooler addresses the critical gap between factory cooling capacity and aftermarket power output, preventing oil degradation and maintaining optimal viscosity during sustained acceleration, high-speed cornering, and extended throttle sessions.

The Oil Cooler DLM -12AN 17.5in x 8.5in features a -12AN port configuration, making it compatible with standard braided stainless steel or PTFE hose assemblies commonly used in modern performance engine bay layouts. The compact 17.5-inch length combined with the 8.5-inch width allows flexible mounting in tight spaces without sacrificing core surface area for efficient heat rejection. Aluminum core construction with welded tank design ensures durability and resistance to vibration-induced failure, while the -12AN fittings provide secure, leak-free connections when properly installed with quality hose and crimped fittings. Weighing just 5.3 pounds, this cooler minimizes unsprung and rotating mass without compromising cooling capacity.

This oil cooler is ideal for LS engine swaps, late-model domestic platforms, turbocharged applications, and custom water-cooled builds where factory oil coolers prove insufficient. Mechanics and engine builders frequently specify FLUIDYNE cooling solutions when upgrading naturally aspirated engines to forced induction or when increasing displacement and compression ratios beyond OEM design parameters. Installation requires basic hose routing from the engine oil filter adapter or sandwich plate to the cooler inlet, then back to the pan or sump—a straightforward modification that yields measurable improvements in oil stability, bearing protection, and overall engine reliability during spirited driving or sustained performance use.
