The more power you push with your 2009 Lexus GS450h, the more the engine needs to be cooled. An aftermarket, high performance cooling fan will provide the airflow needed for optimal heat transfer. At Sport Compact Warehouse we have a large selection of electric fans, higher CFM units, low profile units, and dual electric fans. We carry a large range of sizes and CFM ratings. If you have any questions regarding high performance radiator fans reach out to one of our experienced representatives and we will help you make a more informative decision.
