That's a good question- I understand there's a service bulletin out telling BMW technicians to install oil coolers on all 335is (only when customer's complain?).
And Dinan prescribes a much bigger one. Seems the twin turbos are heating up the engine ALOT more than BMW suspected and they may be trying to avoid a recall.
Still it would be a cool car to own- just not $40K worth of cool IMO.
