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-old oil cooler, but also a performance and fitment upgrade. 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 and hardline bent hoses, which can corrode, be difficult to source, and be expensive to purchase. This oil cooler is built to last with a rugged bar-and-plate design, increased cooling capacity, variable inlet/outlet fittings, and improved dynamic fluid properties. The CSF oil cooler provides the durability, quality, and efficiency these old German "steeds" deserve.
