Long story short. I live in Pennsylvania and drive a 2007 Galant 2.4L with a PremAir radiator. I get OBD code P1546. If I read this correctly I need to replace my very expensive California emissions radiator.

1) Does anyone know if I do not replace the DOR radiator will my car still pass emission for Pennsylvania?

2) If I need to replace the DOR radiator does anyone know where I can purchase one that won't break the bank at over $1000?

I scoured the internet for the better part of a day with unsatisfactory results.
