Probably going to be a good deal more expensive than other HFCs.

 

Only a few of those brands worth mentioning, the rest is eBay crap.

 

A thread from 2008? Really?

Anyway....Kinetix makes a passable HFC and that is the only one I know of but it won't pass a visual. Also, it was only tested as the only mod on a stock Z.

 

Daaang i guess i should have started a new thread
do they have a CO # ?

 

You mean a CARB #? Nope. They are "passable" for emissions, but still not legal in CA.

 

thats the whole point of this thread no carb number means not legal. there are tons of hfc with no carb number

 

CA will never go back on the whole HFC legality. It just comes down to a passable cat that you have a 50/50 chance with the smog guy. I just switch them out a week before my smog test and then switch em back in.
