CSF offers the best and most advanced Oil Coolers on the market. So when it comes to keeping your engine oil temps down as you push your Vehicle / 73' Porsche 911 RSR-Style Bumper hard on the street or track, a CSF is the obvious choice.

The CSF #8111 Universal Single-Pass Oil Cooler was originally designed for direct-fitment as a front mount center oil cooler for Porsche 911/930 models (up to 1989) (for IROC-style or similar front bumper). However, due to its size and mounting capabilities CSF saw the potential for its use in a variety of custom applications.The OEM Porsche oil cooler is now more than 30 years old, and is very hard to find. Used RSR oil coolers go for $3,000+ USD in the resale market. CSF has filled the void for consumers looking for an affordable alternative with new technology and better fitment than the original. CSF's well thought out design featuring a tapered tank with 15 degree inlet/outlet angle is a huge improvement over the bulkier banjo style fittings of 30+ years ago.A Dual-Pass version of the Oil Cooler is available with the same dimensions but with both connections on one end tank (CSF #8111)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.
