This BladeRunner Oil Cooler uses a durable brazed 25-row all-aluminum stacked plate construction that allows for greater efficiency and lower pressure drop than a standard tube-fin design. Designed to work in series with your vehicle’s original transmission oil cooler that is mounted down below. Provides lower transmission oil temperatures to reduce transmission wear and extend life of oil viscosity. The BladeRunner Oil Cooler kit makes installation simple with direct-fit mounting brackets, stainless steel hardware, and leak-proof AN connections. No cutting or alteration of factory hardware is required. Features a durable black finish with a laser-etched aFe POWER logo on the front and includes black-anodized billet aluminum AN fittings for a sleek appearance.
