Once again pro is the only way to go with TSP. You will be blown away by the output of this 1,600 cfm fan. The medium profile of the high output motor still allows for clearance in a tight setup. Pro flow fans are configured as a puller and airflow is streamlined by the deep surrounding shroud design. Since the fan is mounted on the engine side of the radiator, it will not restrict airflow through the radiator core when the vehicle is in motion.
