oil cooling intercoolers are less affected by ambient air temperature and humidity. Air-to-air intercoolers can be less effective in hot and humid conditions, as the ambient air may already be saturated with moisture. Oil cooling intercoolers, on the other hand, are not dependent on the ambient air and can maintain consistent cooling performance regardless of the external conditions.
However, oil cooling intercoolers also have some drawbacks. They require additional plumbing and components to integrate them into the engine's lubrication system, which can add complexity and cost. They also rely on the engine's oil cooling system to dissipate the heat, which means that the oil must be properly cooled to prevent overheating and potential engine damage.
