COLD AIR INDUCTIONS
If you want to bump up the performance and fuel economy of your Chevy Impala, thereÕs a very easy way. Swap out the stock air intake with a cold air intake system from Cold Air Inductions and gain an average of 12 horsepower (or 14 horsepower when measured at the wheels). It will also boost your fuel efficiency, which is always a plus.
