Improves cooling efficiency by channeling more cold air to the radiator. This is achieved by redirecting the air flow that usually escapes over and around the top of the radiator, on to the radiator itself. This keeps coolant temperatures low and in-turn allows you to continue driving aggressively for longer on track.
