I have an Airaid CAI for the 99-06 GM Full Size SUV's and Trucks with the 4.8, 5.3, and 6.0 Engines. The kit comes complete with the Filter, Enclosure, Intake tube, Hardware and the Prefilter(Normally an Extra cost option). This kit is in Pristine Condition and sells for around $300.00 without the prefilter. If in doubt about fitment, you can check the Airaid website. I'm asking $165.00 plus shipping.
