"Intake was somewhat easy to install on my 03 Grand Prix. The instructions were not detailed, but manageable. The performance was great the first two weeks, but now there seems to be a drop-off. It just doesn't have the same roar of the engine that it did when I first put it in. Overall though, there IS an increased performance and I suspect better fuel millage, but as like everyone else, I can't keep my foot off the gas." —Orion M from Brighton, MI bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Pontiac Grand Prix.
"A very well designed and functional aftermarket intake kit. Provides increased performance and is relatively easy to install. Greatly improves underhood appearance." —Greg H from Troy, MI bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Pontiac Grand Prix.
"The K&N 63 is a great first upgrade to my grand prix. I can feel the extra pick-up it gives my car." —Andrew K from Fresh Meadows, NY bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Pontiac Grand Prix.
