A CAI on the V6 cars seems like it would have little to offer vs. the cost.
Here's what I did on mine, years ago, instead: On the factory filter box there is what I call the "nose". A skinnied-down plastic piece the air has to pass through to enter the air box. At its narrowest point you could probably barely fit a quarter through it. Its the only piece in the factory system that looks obviously restrictive, and it is. It's ONLY purpose is to quiet the "intake roar" that the V6 makes on heavy throttle application.
It's held on by 4 rivets. Drill them out and remove them. The "nose" comes right off. You'll notice a much larger circular opening now for air to enter the air box. It has a lip around it that I further shaped to create a more bell-shaped entry to the air box.
Installed a K&N designed for the factory air box and that was it. No big whoop and worked like a charm. You could also hear the intake roar when I went deep into the throttle. Kind of like when you put an open element air cleaner on a carb setup in place of the factory fully-enclosed air cleaner assy. But with the V6 tone to it, obviously, instead of a V8.
And yeah, a 4th gen driveshaft is a bolt-in.

Though there is another option. The snorkel intake from the 2.8 or 305 IIRC, gut the bottom of the airbox that takes the two square filters and you are good to go. Its supposedly the single best intake for these cars. It takes air from in front of the rad, and you can turn it into a ram air intake pretty cheap with some rectangular hvac ducting.
I will see if I can dig up the thread for you.
