I just put that unit in and it's will worth it. It looks really nice and made to last. The workmanship is top notch. I looked at the K&N and just couldn't see how it was suppose to be Cold Air with a heat bracket that looks to still have plenty of heat being sucked in to the intake. Check out my post with Pic's.Anyone have one of these? http://coldairinductions.com/W-BodyLS4V8ColdAirBox.html
I am wondering if they are worth the money?
The 3.9 is part of an all-new family of advanced overhead valve, V-6 engines from GM. Not from the 3.8L or 3800 engine or block or 3.4L.I just bought an Impala LTZ with the 3.9. I don't know much about the 3.9. Is it simply the 3800 engine bored out slightly, or is it the old 3.4 bored out? I was just wondering. thanks
