Dual-Pass Heat Sink Cool er 18in Black Anodized

Derale built this 18-inch dual-pass heat sink cooler (DER13282) for anyone who needs to keep fluids cool in a high-performance vehicle. Modified street cars, track cars, and daily drivers that see extra engine load all benefit from its heat-drawing ability.

A dual-pass layout routes fluid through one section of the core, reverses it inside the manifold, then sends it back through a second pass. This gives hot fluid more contact time with the aluminum fins and pulls heat out faster than a single-pass design. Black anodized aluminum resists corrosion and looks clean under the hood.

Custom transmission loops, differential oil cooling, and engine oil temperature management all suit this cooler well. At 3.03 lbs with dimensions that allow tight mounting, it adds little weight while delivering serious thermal performance across many automotive cooling jobs.
