HGK Water to Oil Cooler (Heat Exchanger)

The HGK Water-to-Oil Cooler is a lightweight, high-efficiency aluminum heat exchanger designed to regulate engine temperatures in demanding motorsport environments. Featuring AN12 male oil line fittings and Ø32 mm male water line ports, it integrates seamlessly into race-spec cooling systems.

Typically installed in-line between the radiator and water pump, it uses the system's coldest water to reduce oil temperature effectively. This ensures both oil and coolant stay within a similar operating range, protecting engine components and sustaining optimal performance under high loads.

Ideal for race and track builds where space, weight, and thermal balance are critical, this cooler is a reliable solution for temperature management.

Key Features:

• Lightweight aluminum construction for racing applications.
• AN12 male fittings for oil lines.
• Ø32 mm male ports for water lines.
• Designed to be installed between radiator and pump.
• Maintains balanced oil and water temperatures for engine efficiency.
• Ideal for high-performance and motorsport cooling systems.
