Do you want more power, performance and torque from your 2005 Impala? You have many options. From installing a bigger engine, which costs a fortune, to install a K&N Cold Air Intake which costs pennies. This cold air intake has been designed especially designed for your engine and uses a washable and reusable K&N air filter. The shell of the cold air intake system reduces the build up of heat and only allows cool air to get to your engine This means you have better air flow into your engine and that gives your more power and performance. All Impala Cold Air Intakes come with a standard 70mm intake and base flange. From there you can use any of the included accessories to make sure it fits on your engine: saddle bracket, bracket fasteners, an expandable 70-mm cold air intake hose up to one meter long and die cut decals. If you have a normally aspired engine up to 250BHP or a turbo engine up to 350BHP, then a cold air intake system is just what you need.
