the so called "cold air intake" was just a high polished pipe still using the factory air box....not my idea of a cold air intake. just buy an aftermarket one. an air box isnt going to mess your car up to make you take it into the shop for warranty work. and if it does, put your old air box back on and take it in to the dealership for service.

I have no idea why GM has never made it, but your reasoning makes sense to me about not being able to improve it. The stock airbox with the snorkel seems like a pretty good piece to me.

Does anyone know if the V6 and V8's use the same airbox? The first thing I would if I was waiting for a V6 cold air kit is see if I could upgrade to the V8. Stock V8 should be plenty of air for the V6. If they are the same, then I would spend the money elsewhere.

I feel like an idiot posting about it now, but I still would like a straight answer from GM. Are you going to release an airbox upgrade or aren't you?

I've waited two years because you (GM) give an answer that you don't recommend doing anything that would void my warranty, and my dealer told me the same thing.

As for the v8 and v6 using the same airbox. They use the same drop in filter, the only difference I can tell is that the V8 airbox has another resonator on the curve after the sensor.

I asked Al Oppenheiser in 2010, he told me October. This last year I asked him and he thought it had been released, but he delayed it from October because it didn't perform well enough.

I used to check once a month, but I don't see why I even bother anymore. I have a feeling that my K&N filter that I dropped in is doing the same thing that the GMPP airbox would do anyhow.

On my L99 when it was stock, no aftermarket CIA increased horsepower worth mentioning, and some lost power. The factory airbox allows for zero intake vacuum.

I always thought of asking you that, but never did, as right after that, the ZL1 Iver showed up.

Sounds like GM did almost too good of a job with the stock airbox.
