It's supposed to give you up to 5 HP, but that's debateable. No, it shouldn't affect your smog check, the K&N CAI is supposedly CARB approved. But IMO, the K&N CAI is just a waste of money with negligible returns for the amount of money invested.

what are you comparing this to?

actually all 3 of teh major CAI manufacturers have CARB stickers on the CAI, K&N, AEM, and Injen. they all produce about 5-9 gains in HP. the only problem with CAI's is that if you drive through a puddle deep enough you will suck up enough water to hydrolock your engine.
