The VTT G8X Billet Oil Cooler Adapter Fittings are the essential building blocks for any custom S58 oiling project. These precision-engineered adapters bridge the gap between BMW’s proprietary connections and the industry-standard -10AN plumbing. By utilizing these fittings, builders can easily adapt the G8X platform for specialized applications, such as full-drag setups that require no cooler or track-focused builds requiring front-mount external heat exchangers. The billet construction ensures a leak-free seal even under high pressure, while the compact design allows for easy installation in tight engine bays. Note that two kits are required if you intend to convert both the housing and the cooler ends of the system.
