CSF Universal Single-Pass Oil Cooler - M22 x 1.5 Connections 22x4.75x2.16

CSF has built a reputation for advanced cooling systems, and their universal single-pass oil cooler is a prime example of that expertise. If you're looking to manage oil temperatures in a custom application, or specifically for a '73 Porsche RSR-style bumper, this cooler offers a robust solution. Its unique bar and plate design is built to handle higher pressures and more abuse than conventional stacked-plate coolers, making it suitable for areas that might encounter road debris.

The design allows for flexible mounting – horizontally, vertically, or parallel to the ground, as long as it has good airflow. The end tanks on this specific model have a 45-degree front angle, and the M22 x 1.5 fittings are oriented straight back, which helps it fit flush within '73 RSR bumpers. For optimal performance, CSF suggests cutting the front tub to improve airflow and allow for a rear fan shroud, which can help pull more air through the cooler at low speeds or when idling. This cooler is versatile and commonly used for engine oil, transmission fluid, power steering fluid, and differential fluid.

This unit comes with a satin black finish for added protection against corrosion and debris. The core measures 18.9 inches long by 4.72 inches high, with an overall dimension of 22 inches long by 4.75 inches high. It's pressure tested to 120psi, and while it uses M22 x 1.5 connections, it's also optimized to accept AN-16 fittings. The triangular flush mounting holes are M8 x 1.25.
