carb approval or not... you can still be illegal with an intake...
the reason they need carb approval is 2 part...
1. More air = more gas in our cars. which in turn creates more exhaust.
2. Some may eliminate the crankcase vent tube or the iat sensor or any number of other emmision equipment that's built into the intake system..
The reason it could be illegal with or without is.
1. Could make your car loud enough to break noise pollution laws.
2. Some states prohibit any modification to the car from stock.
