I looked into those a while back and they look like a filter with a tinfoil box around them. But its either them or KN I haven't found anyone else that mass produces one for the 5.3

The box appears to made of I'm guessing 3/16" aluminum. The inside of the box is covered with some type of heat reflecting material. I think all that appears to be quality, I'm wondering what type of air filter they are useing? Do you think it is a K&N?

Nah, its probably one they made it just looks alot like a K&N. I emailed them asking what kinds of gains are to be expected and what kind they've seen from impala's and grand prix gxp.

Would you go with the K&N? Or do you think they will reply to your email? If so, will you share what they said?
thanks

They do look very similar, only thing I can see is the tubing is different. Plus those were for the older model imps. CAI responded back and said anywhere from 12-15hp gain, but thats what K&N claims aswell. Price isn't that much different about $20 or so. Me personally I think I'm gonna go with the K&N just for namesake.

I'm trying to find out more about the air cleaner that comes with it. I'll pass along what I find out.

CAI is worth it.

Anyone have one of these? http://coldairinductions.com/W-BodyLS4V8ColdAirBox.html
I am wondering if they are worth the money?
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.

3.9: what is its derivation?

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

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.

awesome info.

I am really interested in performance mods for my 3.9 but it doesn't seem like there is anything really bolt on ready.

Are you being smug to prove some kind of point? or is it for your own amusement?

I simply responded to a "related thread" where I felt value was added. I did not realize there was a date stamp.
