Product Description

It's no secret that the N55, when driven under high loads for sustained periods of time or in high ambient conditions, it has an engine oil temperature problem. 
Owners often see temperatures in the region on 130°C + and often going into the 140°C+ region if care isn't taken. High operating temperatures can reduce the longevity of engine components and ultimately result in failures, sooner. 
To give owners more engine cooling performance which can allow them to drive their car harder for longer in the same conditions, CSF has developed a unique oil cooler upgrade for the N55 equipped cars.
