Quote:
Required Products In order to qualify for Dinan’s matching new car warranty coverage, which includes consequential damages, the vehicle MUST be equipped with either a factory oil cooler (not all 335s were equipped from the factory with an oil cooler) or Dinan’s High Capacity Oil Cooler (recommended).
