Well I finally got around to doing the install on a Cold Air Intake kit from PSM Manufacturing as seen in the last TDR. Although this kit for my 2003 ran a little more than I wanted to spend "Santa" got it for me, and there are no moving parts and nothing to wear out so I guess it is worth it. The instructions, with pictures were very easy to follow and the total from start to finish time was about an hour. Havent had it long enough to report on the EGT results but it has to help lower them. You can view the kit at www.psmbuick.com and the price was $130 to my door.
