Radiator ducting
Bought and fitted this a year ago. Im not sure if cooling is helped with fan working in traffic as I'm no engineer but no overheating problems at all (touch wood). It's so we'll made and must move air in a more efficient manner especially on the go. You can't go wrong with the price just for a little more reassurance.
One year on when the sun shines on the front of the car it still looks the business behind the grill.. What more do you want.
