My second K&N air filter, this one for my Grand Prix GXP. My other one is in a 2004 Grand Am GT. There are over 40,000 miles on that filter without a problem. I had an immediate jump of over one more mile per gallon in the GXP. And it makes my wife and daughter happy because it doesn't contribute to landfills like other air filters do! Adding a K&N air filter should be one of the first things anyone does after purchasing a car.

Although the install process was a bit envolved which included the remounting of the transmission and engine management computers, the work was worth it. The additional power created by the upgrade is most evident.
