Description

Part #: 7089

As more enthusiasts push the performance limits of F-Chassis BMWs, the factory radiator has started to show its age. Increased boost and upgraded turbos generate significantly more heat, and the stock system can struggle to keep up. Combined with the heat exchanger mounted in front of the radiator, engine coolant temps can get too hot, especially during track use which can trigger limp mode.

The Focus RS was very well engineered and performed admirably out of the box. However, a few upgrades can quickly lead to heat issues, especially on the track or in hot climates. An upgraded radiator from CSF is the perfect solution.

MIA's Description

CSF has over 5 decades of experience manufacturing radiators. The CSF #7089 was designed as a drop-in fit replacement for the BMW OE 17118482623 only. It will NOT replace the OE 17118652497 found on early F3X 340i/440i with build dates up to 07/2016. If you are unsure of which radiator you have, you can visually check or call a BMW dealership with your VIN to verify. The CSF #7089 & OE 17118482623 have a single connection on the lower left hand tank for the auxiliary radiators. The OE 17118652497 has two connections for the auxiliary radiators. It may be possible to convert an early model vehicle that came with the OE 17118652497 using the newer coolant line setup, however this has not been verified.
