is the R2C street legal in CA?

 

I'm using the k&n typhoon setup on my G37S. I elected to go with the ram rather than the cold for 3 reasons.
1. The oem air ports ram right into the filters
2. I was a little worried about moisture because the cold are installed in front of the radiator.
3. Rams installed in about an hour and I didn't have to take apart my car like I would have had to do with the cold.

After install, the typhoons changed the power curve ALOT.

Fairly inexpensive and well worth it IMHO.
