Each cooler has a custom CSF core, developed with CFD analysis and testing, about 100 percent larger in volume than the factory unit per side, with one-piece seamless air-inlet end tanks with integrated charge pipes, 100 percent TIG-welded cast end tanks, OEM-style quick-connect water connections, and dual 1\/8 NPT methanol or nitrous ports on the outlet tank. It is sold as a complete left-and-right set with hardware in a crinkle black finish. Installation requires minor work: the mounting pins the coolers rest on need to be shaved down and the air-balancing tube trimmed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: liquid-to-air charge-air-cooler set (left and right)\u003c\/li\u003e\n\u003cli\u003eCore: custom CSF, about 100 percent larger than OEM per cooler\u003c\/li\u003e\n\u003cli\u003eConstruction: one-piece inlet tanks with integrated charge pipes, 100 percent TIG-welded cast tanks\u003c\/li\u003e\n\u003cli\u003ePorts: dual 1\/8 NPT methanol\/nitrous on outlet tank\u003c\/li\u003e\n\u003cli\u003eEngine: twin-turbo 4.4L V8\u003c\/li\u003e\n\u003cli\u003eFinish: crinkle black\u003c\/li\u003e\n\u003cli\u003eFitment: complete set; minor work (shave mounting pins, trim air-balancing tube)\u003c\/li\u003e\n\u003cli\u003ePart number: 8351\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVehicle Applications\u003c\/h3\u003e\u003cp\u003eDirect fit on the following (4.4L V8):\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2025 BMW M5 (G90)\u003c\/li\u003e\n\u003cli\u003e2026 BMW M5 (G90)\u003c\/li\u003e\n\u003cli\u003e2025 BMW M5 Touring (G99)\u003c\/li\u003e\n\u003cli\u003e2026 BMW M5 Touring (G99)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat vehicles does the CSF 8351 fit?\u003c\/h5\u003e\u003cp\u003eThe 2025-2026 BMW G90 M5 and G99 M5 Touring with the twin-turbo 4.4L V8.\u003c\/p\u003e\u003ch5\u003eHow much larger are the cores?\u003c\/h5\u003e\u003cp\u003eAbout 100 percent larger than the factory coolers, per side.\u003c\/p\u003e\u003ch5\u003eIs it sold as a pair?\u003c\/h5\u003e\u003cp\u003eYes.
