At the same time the panel was designed to keep the air going into the radiator through the engine bay without escaping out from under the engine bay which can also improves cooling on the track. It is a direct replacement over the stock unit that is often missing from the S13 240SX. Made from durable 2mm thickness plated aluminum.
