If the shop is actually concerned about CARB stickers they will most likely run the EO#s. Just saying CARB approved means nothing. If they run the EO#s and they don't match model year and motor size, it will fail. As far as I know, there are no CARB legal intakes for 03 2.3 Duratec.
Used Cosworth is the only "legal" intake for that year. I had my car smog'd earlier this year in California before I moved to Mississippi. Now I have no smog whatsoever
I would think you could easily pass inspection with the K&N though. The smog guys don't typically run numbers.
There are a couple Cosworth used units in the classifieds though.
