Why no factory CAI?
I was thinking to my self... In the case of aftermarket Cold Air Intake systems like rotofab or K&N, Why GM didn't use this kind of CAI project in their assembly line? it wouldn't cost more and would give 10 to 15 hp to the engine (as said by the rotofab and K&N)
 what would be good to sell when comparing to another models...I would like to know why... may be a stupid question, but I didnt' get the answer yet... |

I suspect it has something to do with the desire to suppress intake noise to meet regulations, or the need to protect against water intrusion.

Vehicle engineers have many factors other than just maximum performance to consider when they design OE intake systems (noise, fuel economy, emissions, etc.) and in the process leave plenty of room for the aftermarket to make improvements.

I think factories stay away from oiled filters as well, for the possibility of it fouling sensors

Like someone else said: water intrusion.
Some people actually use Camaros as daily drivers, and get caught in clouud bursts. That would be me, for example. |

Does the CAI really give 10-15 more HP or is it just a gimmick and a waste of money ?

They can give that much depending on the model of car and other mods.
I had a Mazda 6 a few years ago that had a really crazy intake 'baffle/resonator' system that significantly reduced the intake noise (engine growl). Just taking that off would really wake up the engine, and going to a full CAI did even better. Even the Camaro most likely has been designed with sound in mind.

To think of a few reasons.... water, snow, dust.. ingestion specs. EPA regs requiring that funky carbon absorber pad to be sealed in the air box. Oiled filters somtimes muck up the sensors. Noise specs... probably more.
And yes a good CAI can give a nice hp increase, much worth the money for the good ones. Great performance, but would probably not pass any of the OE specs they are constrained by. |

I have a roto-fab with the oiled filter & I have cleaned & re-oiled it twice so far with no problems at all!!!

No one has actually proven that the stock intake is restrictive. LOT'S of CAI's have a huge amount of placebo effect. People swear it SO much faster now when in reality its not. Those K&N exposed filters are junk (no offense to owners). It just sucks up a bunch of hot air from the engine bay.
There are a couple brands that seem to show positive results but like posted above GM has to worry about more than maximum power. |

The question is, why didn't the GMPP cold air intake ever get released?

Hmmm....we have been testing CAI's for the past 12 plus years and almost all (if we like them or not) make definate dyno AND 1/4 mile gains....substantial. But back to the OP question, unless you get into the super car realm, there is always a balance of cost, performance, economy, liability, and above all else no matter what the engineers reccomend, between the marketing to the different demographics and the been counters, even a fraction of a cent over budget can get nixed and then its a dead issue. And, if you look at the intake boxes of today VS 10 years ago, most incorporate some sort of cold air entrance to some extant. Not near what the good after market units give (CA Inductions my favorite), but leaps and bounds over the ones jsut a few years ago. Look at a 2011-2012 chrager or challenger....they are a true cold air intake that just needs a better flowing filter and of course a smooth coupler is far more volumetric efficient tha a accordian style. Good question though and if let loose with no budget and other contraints the engineers would put out some "sky's the limit" vehicles as the talent is there.
