Isn't this a spider of an oil filter adapter? Here we see the system configured with the oil-to-water “brick” heat exchanger and pressed-in hose nipples as used with standard cooling. With Track Cooling the oil thermostat replaces the “brick,” the hose nipples are deleted, and the spider is machined to accept SAE O-ring-type, threaded, stainless steel hose connectors. SVT says they don’t use AN fittings because they tend to loosen from vibration. The black hex seen under the “brick” is covering the pressure bypass loop (a spring-loaded pressure relief valve) used with Track Cooling. The same oil filter is used on all 5.4 and 5.8 engines.
