I believe you've said exactly what the rest of us are thinking and I don't think anyone disputes this. Please don't take offence to this, but the confusion I believe is partly because a GM dealership provided different information (which is obviously in question). I'm the first to agree that often dealers don't know the vehicles as well as they claim. Having said this however, we have a situation where the dealership says one thing and a member on an internet forum who hasn't provided background, experience or other credentials says something else. Personally, I always like to have solid proof that the "experts" (GM) have provided me misinformation and understand how/why they are wrong before I accept information from an "unknown" source. Again, this isn't meant to suggest you aren't familiar with this since obviously you are. It'* only to provide further evidence that what the dealer provided was wrong.

No offense taken. I worked in those GM service lanes for several years. I know what they know and don't know.

That hose has been reported missing here in the Forum before, and in the photo, that nipple looks untouched by a hose. Seem in the earlier incident someone said it was discussed on a Caddy forum. We have had several members over the last 4 years that have had missing parts right from the lot with GXP'*, including me. So nothing surprises me. I didnt even know there was an air dam when the roof opened untill I seen one in a post here. Trunk access door another one I remeber reading. Cabin air filters on some GXP'* and not others. Quality control at the plant and at the dealership prep isnt what it should be. These are $40,000 cars and a sham for the sticker price. But thats all old history here now........

Yea, mine never came with one (a cabin air filter).

FWIW, I removed my stock air box (I put it back in during winter), in favor of my CAI I mocked up from a couple spare GTO CAI parts. Anyway, I don't even have this tube connected. No biggy. It'* not used after 240 seconds of initial operation (or once into closed loop operation... whichever comes first) anyway, so...

Did you really feel any diff with CAI?

The cabin air filter became a dealer, not factory installed option after a certain year (although I don't remember specifically which one). I had to add it to my 2004 as well. I just don't understand their logic sometimes.

We had a poll here back in the day, andway less than half the GXPs came with the cabin air filter. It turned out, there is an RPO for it of all things. And naturally mine didnt have it.

No loss personally. I opened up the trap door one day and commented "Gee, that'* nice, nothing there!"

I found the RPO code. K12 indicates you got the filter. $40,000 and its extra for a cabin filter. snicker..............

Now we just need to find out what a GM replacement filter costs. That'll be $195 please. LOL!
