A great modification for daily drivers and track cars alike, an upgraded transmission cooler maintains optimal oil temperature for extended periods of time under aggressive driving conditions. This is even more critical for vehicles producing more heat than from the factory, such as heavily modified builds, those running any sort of forced induction system, or vehicles with aftermarket TCU tunes.

Not only will the C3 Transmission Oil Cooler offer significantly better cooling and extend the life of your transmission, but it will also be much more durable and longer lasting compared to OEM. Although it is larger in size as well, it fits within the OEM bumper with no cutting and attaches to all factory oil lines.

Product Details

The Concept 3 by CSF Transmission Oil Cooler is a plug and play solution engineered to combat high transmission temperatures often seen in the Kia Stinger & Genesis G70. Designed in collaboration with Concept 3, this system offers motorsport-grade performance in a drop-in fit form. The result is improved thermal management and long-term transmission protection under sustained load and high-performance use.

Design & Engineering

At the center of this cooler is a dual-pass core featuring CSF's proprietary AC Condenser Technology. This core utilizes a Super-High Pressure 26mm 10-Channel Microtube architecture that maximizes both oil flow and cooling surface area. The dual-pass configuration offers extra heat dissipation by increasing the time the transmission fluid is in the cooler. The result is dramatic temperature reduction under all driving conditions.

Concept 3 by CSF vs OEM

The factory transmission oil cooler for the Stinger and G70 is definitely undersized and just enough for daily driving. Add in modifications like a tune or larger turbos, the transmission starts to get too hot. Even spirited street runs or light track use can cause problems. The CSF transmission oil cooler is a must have for any type of performance oriented driving offering:

  • Estimated 130% Increase in Cooling Performance
  • 185% Increase in Heat Exchange Area
  • True Dual-Pass Configuration for Better Cooling vs. OEM Single-Pass
  • More Than Double the Size of OEM
