Unlock reliable oil temperature control for the BMW 335is (E92/E93, 2011 to 2013) with this genuine Dinan high capacity lubrication cooler. Built for spirited driving and track days, it delivers the thermal headroom the N54 twin turbo needs for consistent power, lap after lap. If you are chasing an uprated oil radiator for the 335is that installs cleanly and looks factory, this is the bolt-on solution enthusiasts trust.
Engineered to outclass the stock unit, the Dinan core offers two times the fluid capacity and a dramatic jump in heat rejection. Cooling tube area increases to 414 sq in compared with 112.5 sq in on the OEM cooler, helping control lubricant temps under sustained load. A neatly integrated feed duct improves airflow to the core, while an enlarged discharge to the wheel arch aids evacuation for better efficiency at speed. It mounts to the original points for an OEM-style fit and finish, with lightweight convoluted PTFE lines wrapped in a durable polyester braid and secured by motorsport-grade fittings.
