BMW B58 B48 Charge Cooler Radiator 17118741830
Genuine BMW charge cooler radiator for B58 and B48 engined 1, 2, 3 and 4 series cars.
It is very common for these radiators to become damaged by stones and other road debris, which make small puncture holes in the radiator allowing the coolant to leak out of the low pressure circuit.
This will stop your charge cooler cooling the charge air, causing high IAT's and a drop on power.
