CAI is actually worse on gas mileage...believe it or not

A CAI will increase MPG. Any increase to efficiency increases MPG. If the energy to pull air into the engine decreases, as it does with a CAI, the energy used to pull air in turns to energy to drive the car forward. The only reasons a CAI would decrease MPG is 1: Because a PCM couldn't properly read the MAF due to a bad install or 2: The driver gets a heavy foot to enjoy the added power. The main purpose of a modern air box is to both house the air filter and quiet the intake noise.
