Chase Bays 92-99 BMW 3-Series E36 (w/M5X/S5X) Oil Cooler Kit

The oil cooler core in this kit is a compact 10-row unit, measuring 10" x 5.5" x 2". This size is chosen to fit neatly within the E36 chassis without requiring major modifications, while still offering a good surface area for heat dissipation. It’s designed to help manage oil temperatures, especially when your M5X or S5X engine is being pushed hard, like during track days or spirited driving. Keeping oil temperatures in check is crucial for engine longevity and consistent performance.

Chase Bays has put together a complete package here, including everything you need to get this installed. You'll find braided stainless steel lines, which are known for their durability and resistance to expansion under pressure. The kit also includes all the necessary fittings and adapters, all designed to work with your specific BMW 3-Series E36 model equipped with either an M5X or S5X engine. The goal is a clean, reliable installation that integrates well with your existing cooling system.

When installing this oil cooler, pay close attention to how the lines are routed to avoid any potential kinks or rubbing against moving parts. The kit is designed as a direct fit for the specified BMW models, but as with any performance upgrade, careful installation ensures it performs as intended. This kit is a solid choice for E36 owners looking to add a robust oil cooling solution to their performance builds.
