Air Diffuser Plate
Having a decent amount of aluminium sheet laying around, I thought I would make myself an air diffuser plate. What these things do is to force the air coming in through the front grille to go through the radiator rather than over the top. Seeing as they are virtually non existant for my car, I built one.
Here is the completed item. It was simply a matter of measuring and tracing the small plastic piece that was originally there (and did nothing) to get the right curve for the grille, then measuring and bending the rest to suit the radiator support and latch.
