CSF Radiators 8103 BMW M2 F87 N55 M-DCT 7-Speed Transmission/Gearbox Oil Cooler Upgrade - Dual-Pass Heat Exchanger, Direct-Fit Drop-In OEM Replacement, Twin-Clutch DCT Cooler Kit, Track Day Overheating & Limp Mode Fix (F87/LCI)

BMW F87 M2 M-DCT Gearbox Cooler Upgrade by CSF – Part Number CSF 8103

Keep your paddle-shift M2 performing at its best. This CSF dual‑pass transmission oil cooler is a direct-fit, motorsport-grade heat exchanger designed specifically for the N55-powered F87 M2 with the 7‑speed twin‑clutch gearbox. It tackles high oil temps that lead to power reduction and limp mode, giving you stable thermal control on spirited drives and during hard lapping.

Built around CSF’s high-pressure AC condenser-style microtube technology, this lightweight, efficient cooler replaces the restrictive factory single‑pass unit with a twin‑pass core for significantly better heat rejection. Expect faster temperature recovery, more consistent gearbox behaviour and the confidence to stay on it longer. We have installed and run this unit on our own builds and customer cars with excellent results, and feedback has been overwhelmingly positive.

What you will notice

• Reliable reduction in gearbox oil temperatures on road and track
• Helps prevent power loss and limp mode when pushing hard
• Improved consistency session after session with quicker cooldown
• Protection for clutch packs and mechatronics during extended abuse

Why this CSF cooler

• Twin‑pass, high‑efficiency core for maximum heat rejection compared to stock
• Approx. 40 percent more efficient than the OE cooler based on CSF testing
• 1‑row, super high‑pressure 26 mm multi‑channel microtube construction
• 12 micro‑channels with dense multi‑louvre fin pack for superior airflow and cooling
• Direct‑fit replacement that reuses factory lines, brackets, shrouds and ducting
• No cutting or permanent modifications required
• Perfect complement for remapped Stage 1 and Stage 2 N55 cars

Ideal use cases

• Track day, sprint, time attack and drift M2 builds
• Fast road cars that see repeated high‑load pulls
• Owners who have experienced overheating or heat‑soak induced intervention
