30 Inch Dual Pass Heat Sink Aluminium Transmission / Engine Oil Cooler

This compact heat sink is ideal for cooling transmission fluid, engine oil, and other automotive fluids. Its dual pass design features external and internal fins that maximize heat transfer with minimal airflow, keeping fluids cool and performing efficiently. At only 3 inches in diameter, the core can be mounted in tight spaces like frame rails, under radiators, and along floorboards. Its satin aluminum construction remains warp- and twist-resistant despite its thin yet high-quality material. Ports and supplied barbs are 1/4 inch NPT to integrate smoothly into cooling systems. This 30 inch heat sink effectively transfers heat even in confined areas so fluids stay at optimal temperatures.
