CSF Oil Cooler Upgrade with Adapters - E30 325e/325i/M3

Here is the replacement E30 oil cooler that you've been waiting for. The CSF E30 Oil Cooler upgrade is slightly larger for more fluid capacity and uses a bar & plate design for maximum performance. The CSF oil cooler works with stock factory lines* or with -10AN fittings with the included AN adapters. With factory replacement oil coolers shooting up in price (over $637 list) this is by far the best alternative replacement with upgraded performance as well! It's even finished in a stealthy matte black paint to maintain an OE appearance. Also works great in SpecE30 and M20 swaps in 2002 and E21!

This is a direct fit replacement on 1988-1992 E30 325i that came stock with the factory oil cooler.

* - For pre-1988 325i and all 325e models this will work with additional parts. You will need the 1988+ oil cooler lines and the oil cooler mounting bracket kit (see below). Requires drilling into your front valance/radiator core support.

For all E30 M3 models you will need the oil cooler mounting bracket kit and custom -10AN lines.
