xxMichaelAnthony He doesn't have the stock one anymore and finding a CARB legal one is way cheaper than buying a stock one.

quacking05focus Just keep your stock setup, buy an adapter coupler for ~20 dollars or less so every two years you can reinstall the top part of oem intake just with the aftermarket unit's filter to drive to the smog shop and get tested. It really takes less than 30 minutes and you don't even have to put the car up on jacks or anything (the biggest pain of course is the large oem air cleaner assembly). I've been enjoying my fs werks for the last three and a half years.

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.
What is the EO number on your Cossie intake? Im just giving the OP info on what actually is CARB legal for his year and what isn't. If he wants to get one that is just "CARB legal" for the Duratec he can go for it.

- Cossie EO# D-594 (04 2.3) http://arb.ca.gov/msprog/aftermkt/devices/eo/D-594.pdf
- Cossie EO# D-594-1 (03-04 2.3, 05 2.0) http://arb.ca.gov/msprog/aftermkt/devices/eo/D-594-1.pd

OP - The part number listed on both EOs is the same. If you end up with the Cossie intake and it isn't the -1 number, print out the second pdf I linked above. Show them the part number is the same and the original EO was just updated to cover more models. And remember I am assuming the smog guy you're going to is doing everything 100% by the book. They might pass it just because there is sticker on it and not run the number.

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.

None of these are CARB approved for 03. Remember, we're in the great state of Commiefornia.

xxMichaelAnthony Your best bet is to find someone local and see if you can borrow their stock intake. You probably wont find a CARB approved intake for under $250 even then I don't think anyone made them for your year.
