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

When you're looking to keep your engine oil temperatures in check, especially under demanding conditions, this CSF Universal Dual-Pass Oil Cooler is a solid option. What you get in this package is the oil cooler itself, featuring a unique bar and plate construction. It's designed with M22 x 1.5 inlet and outlet connections, and the core measures 18.9 inches long by 4.72 inches high by 2.25 inches wide, with overall dimensions of 22 inches long by 4.75 inches high by 2.25 inches wide. The satin black finish offers protection against corrosion and debris, and the "Aero-Flow" bar design contributes to its lightweight strength and maximum flow.

What sets this CSF cooler apart is its dual-pass design and the flexibility it offers in mounting. Unlike conventional stacked or plate-type coolers, this unit can be mounted horizontally, vertically, or parallel to the ground, as long as it has proper airflow. The inlet and outlet port placement is also more straightforward, simplifying oil line routing. This robust construction is built to withstand significant vibration and debris, making it suitable for areas prone to high impact from road elements, such as the front fascia or side vents. The custom end tanks have a 45-degree front angle, and the fittings point straight back, which allows it to fit flush inside '73-style RS bumpers. For optimal airflow and performance, CSF recommends cutting the front tub to allow air to exit behind the cooler and underneath the vehicle, and this modification also provides clearance to add a rear fan shroud for better cooling at low speeds or while idling.

This versatile cooler is commonly used for engine oil, transmission fluid, power steering fluid, and differential fluid in universal applications. It's pressure tested at 120 psi, ensuring its durability. While it's designed for a direct fit in Porsche '73 RS style front bumpers, its universal nature means it can be adapted to many custom setups. For the best performance, ensure adequate airflow is maintained, and consider the recommended modifications for optimal heat dissipation.
