CSF BMW E30 Oil Cooler w/ fittings for OEM style and AN-10 male connections

The CSF BMW E30 Oil Cooler represents a significant advancement in cooling technology for one of the most iconic vehicles in automotive history. Designed as a direct bolt-on replacement in an OEM style, this oil cooler integrates the latest innovations to meet the demands of both classic restoration and modern performance upgrades. It is engineered not only to fit original BMW E30 models but also accommodates vehicles equipped with M20 engine swaps, making it an exceptionally versatile component for enthusiasts and professionals alike.

In collaboration with CA Tuned, a leading BMW restoration R&D partner, CSF has developed this oil cooler to surpass the limitations of the original 25+ year-old unit. The result is a product that offers enhanced durability, improved cooling efficiency, and superior fitment. One of the standout features of this oil cooler is the comprehensive fitting kit included, which supports both OEM style connections and -10 AN male fittings. This flexibility allows users to replace the outdated rubber and bent hardline hoses—components that are prone to corrosion, difficult to source, and costly to maintain—with modern, reliable AN-10 lines.

Constructed with a rugged bar and plate design, the CSF oil cooler maximizes heat dissipation while ensuring structural integrity under demanding conditions. The cast end tank design contributes to the unit’s robustness, while the matte black finish not only enhances its aesthetic appeal but also provides additional protection against environmental factors. These qualities collectively ensure that the oil cooler delivers consistent performance and longevity, qualities essential for maintaining the health and efficiency of your engine.

This oil cooler is particularly well-suited for the BMW E30 models produced between 1988 and 1992, including the 325i, 325is, and 325iX trims powered by the 2.5L inline-six engine. Additionally, for earlier E30 models from 1984 to 1987 and the E30 M3, the CSF #8092 oil cooler can be installed using a Genuine BMW Retrofit Kit available through authorized OEM parts suppliers. This retrofit requires specific BMW OEM components such as body brackets, rubber grommets, grommet inserts, hex head screws, and oil cooler O-rings, ensuring a seamless and secure installation that maintains factory standards.
