thats how i built mine! otherwise you can build a custom one out of a sheet of aluminum. some fancy bending and rivits

the way we looked at it is a sheet of aluminum cost $65 in our neck of the woods plus all the time of bending and shaping and blah blah blah or we could just buy the premade one for $70 and just run it. just make sure you get the right width for the radiator your run.

When we went to a double pass radiator, Howe shroud, and 17" flex fan we went from running 240* during features to 200* and the flex fan made the motor feel way more responsive! even on the hottest days
