K&N Cold Air Intake for 2006-2009 Trailblazer, Envoy, Rainier, Saab 9-7x with the 4.2 L I6 engine and with the mass air sensor. This is the chrome 77 series used for only a month. I also upgraded all the hardware to stainless steel and the filter was changed to their Xtreme open top as seen in the pics. Increases both horsepower and mpgs!!!! These go for close to $300 new and again only a few hundred miles on it and virtually new!!!! I hate to see it go but $120 or make me a reasonable offer. If interested contact Paul at 224-238-9140. Pictures are available. Cash or Paypal
