Radiator duct TR3A/B from TS22014 self-colour (Grey/black). This duct was supplied originally colour coded to the car paintwork. This is no longer practical so the duct is supplied untreated. It can be painted car colour if required.

As this is a standard part we do not have fitting instructions and would usually expect customers to rely on what is available in the workshop manual. In this case, none, which is not very helpful.
