are there any avail that are CARB approved? Thanks.

Intakes do not have to be CARB approved, due to Appendix K of the CARB rules.However, it's worth pointing out, that an intake will do absolutely nothing for your car.At best, you MIGHT see a few horsepower, at certain RPM. Which I'm sure is what you were all excited about, when you were looking at advertisements.Look at the whole dyno, though. You'll lose power in your lower rpm. Which means slower acceleration. Which is one reason why an intake, exhaust, and headers, generally do not increase 1/4 mile time in the slightest.http://www.importtuner.com/tech/powe...index.htmlTake a look. All of the dynos include negative numbers. But for the final result, all they do is take the max horsepower. Completely ignoring all the negative sections. It's a scam.So, if you want to make your car go slower, you're on the right track.

^^^ Your completely right about that Intake Header Exhaust doesn't increase 1/4 miles it decrease it.I own a 2006 Civic SI after adding Injen Cai, DC Race Header and a Electronic Cutout, I manage to extract 30whp. Look at the dyno sheet (http://img108.imageshack.us/img108/5...deltafx9.jpg). There were considerable gains across all the powerband with the mods. On this car if you add only a CAI you will not feel a difference right away, if you add only a race header you wont feel a difference neither if you add only a exhaust. They don't work alone but if you combine all the basic three mods then you will definitely feel the difference, right away.And for the ones who say that an intake won't do any harm with the emissions, they must know that an aftermarket intake system that doesn't positions in a correct place the MAF it will end up messing up the air/fuel mixtures. Don't believe it go to you're nearest dyno and play with your MAF sensor if you car have it.Regarding the main question the only CERTIFIED Emissions Compliance - 50 State Legal Intakes for the Civic SI are the ones from AEM.
