Oil Coolers

Oil coolers together with filter sandwich adapters, oil thermostats, and the hoses and fittings needed to plumb the circuit. A cooler holds oil temperature in the range where viscosity still holds up, which matters on track, with boost, and under sustained load. Core size and the number of rows, port sizes in AN standard or the adapter thread, and the mounting position decide the choice; a thermostat holds flow back until the oil is up to temperature.
