CSF Universal Signal-Pass Oil Cooler (RSR Style) - M22 x 1.5 - 24in L x 5.75in H x 2.16in W

The unique design of CSF's oil cooler line has distinct advantages over conventional style oil coolers (plate-type/stacked oil coolers). The oil coolers can be placed in tighter spaces or different areas of the vehicle that don't have much vertical surface area. Longer rectangular sizes can also help with avoiding the stacking of too many coolers which may cause airflow issues to other components in the cooling system. Inlet/outlet port placement is much easier to route oil lines. Typical oil cooler lines have to be routed from different/opposite ends of the cooler often facing up or down. Usually one line has to run across from one side of the cooler to the other to then be routed together to the feed/return connection of the oil system. The CSF oil coolers are much more robust, durable, and can withstand a higher peak burst rate. This allows the cooler to be mounted in areas that might get high debris (front fascia, diff cooler, side vents, etc...). The CSF oil cooler is designed to withstand a tremendous amount of vibration and debris.
