Constructed entirely from aluminum and finished with a durable black powder coat, this oil cooler offers excellent corrosion resistance and a sleek OEM aesthetic behind the grille of your BMW E30. Whether upgrading for racing or restoring for daily driving, this cooler is engineered to meet demanding performance needs, providing reliable, long-lasting cooling capacity. Installation is straightforward, with a direct-fit design that requires no modifications unless specified, and it includes a fitting kit compatible with OEM and -10 AN connections. The product’s robust cast end tanks are fully TIG welded, ensuring leak-proof integrity and durability over time. Suitable for all E30 chassis models, including the BMW M3 variants from 1988 to 1991, this oil cooler is the ideal upgrade for enthusiasts seeking enhanced oil temperature management during spirited driving or racing.
