Developed along with leading BMW restoration R&D partner CA Tuned, CSF has been able to incorporate many features into its drop-in fit E30 oil cooler. This makes the new CSF E30 oil cooler not just an option for customers looking for a high-quality OEM replacement for the 25+ year oil cooler, but a performance and fitment upgrade as well. One of the most innovative features of this new m20 engine oil cooler is the included fitment kit allowing users to run -10 AN lines instead of the older OEM style rubber & hardline bent hoses which can be corroded, hard to source, and expensive to purchase. This oil cooler is built to last with a rugged bar/plate design, increased cooling capacity, variable inlet/outlet fittings, along with better dynamic fluid properties. The CSF oil cooler provides the durability, quality, and efficiency these old German "steeds" deserve.This Part Fits:

Cheap and does the job
Size: 6 Feet
Seems to be well constructed, it’s a little thinner than I expected, but it passes bass just fine to my SVS PB 2000 Pro.

Great value for high quality lights
Size: 2Pcs 7.6Inch Light Bar
These are really nice lights. Night and day difference between these and the cheap Nilights. They should really try to differentiate these in their listings.
Nice consistent beam pattern and color. High quality build. Power output close to claimed rating.
