Product Overview

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.
