CSF 8092
Lets face it, the stock oil cooler on your 325i or M3 is probably pretty beat up by now. Their location at the very bottom of the front end means they are exposed to the most amount of road debris, and they tend to end up leaking. Pair that with the fact that they are 35 years old, and it's probably time for a replacement. This CSF direct replacement oil cooler is designed with much newer technology that is not only stronger and more durable, but saves weight and cools better at the same time. It comes with 4 fittings; 2 to use your stock cooler hoses, and 2 to run -10 AN fittings in case you want to upgrade your lines as well. What's not to love?
Fits E30 325i/is/ix from 9/87 and E30 M3.
