This is a set of factory Genuine BMW Euro oil cooler lines, as originally used on the Euro-spec E36 M3 and the MZ3 S54. These lines allow the use of the factory BMW Euro oil cooler for the 6 cylinder model E36, and are a common upgrade on US-spec E36 6 cylinder models. The inlet and outlet lines are sold together. New o-rings are sold separately, see Related Items below.
This oil cooler piping can either be used for replacing damaged / leaky Euro E36 M3 oil cooler lines, or for a retrofit on cars that didn't come with an oil cooler. These lines have a lot fittings where rubber hose meets metal line. These fittings are compression crimp-style swage ("swedge") fittings that are very common in the automotive world. Over time, these swage fittings are a common area for oil leaks. It's easier to replace the entire line with a new part than to try and repair the line.
These lines are also very useful if you are doing an S54 swap, and using CSF's S54-swap specific radiator and oil cooler upgrade. Using these Euro hard lines makes install easier in that case.
