Try Wolf Espenhahn at Airlink in Florida:  wolf@airlinktech.com.  They have made NACA vents for air vent and oil cooler applications.  I have their oil cooler unit, but it is several years old.

Several years ago, the Lancair Network News listed a source for a premolded NACA scoop with a 3" round outlet that's suitable for our oil coolers. I need another one; however, that source no longer seems to be in business. Does anyone know where such a NACA scoop can now be purchased?

Thanks,
