I just realized that I have never included a video of my CTS since I got the volant intake installed. It'* basically a cold air intake that'* supposed to net around 8-12 HP. The stock intake was horribly designed. Here'* a WOT video and some pics.
*especially watch what the RPM'* do after 3,000 when the TC is on.
The RPM'* fly after 3k but are pretty slow building before it.
It'* a little slower than when I first bought it because I only run 87 in the winter, and usually 91 during the summer months.
(plus lets face it, winter blend gasoline sucks!)
