Why can't the SULEVs get a high-performance radiator? I know CSF Racing makes some for the N52s...

I live in California and own a SULEV (I love that I can tell "lesser" lovers of the environment in California that my car is a SULEV), so starting this year I'm subject to bi-annual smog inspection. The SULEV radiator is equipped with a "PremAir" catalytic coating that converts ground level ozone into oxygen using the heat dissipated from the engine. There is a sensor, and the car will throw a code if the sensor is gone or malfunctioning.
EDIT: I would be very pleased if one of the high-performance radiator manufacturing companies made a true performance radiator for the BMW NA SULEVs. There are hundreds-of-thousands of them.
