Well the stock air box is pretty restrictive.

 

I wouldn't say it is pretty restrictive...look at what the car can do stock...might be too restrictive for a 6.0L V8, but it is fine for a 2.0L...they just need a bit more air flow to get us another 30 HP...

 

I think that's what restrictive means. It restricts airflow.

 

No the stock box and filter is very restrictive.

You mean to tell me that using the same setup as a 2.2 and 2.4L N/A cobalt on a 2.0L Turbo car is not restrictive. That would mean the N/A cobalts don't need a CAI cause they flow so well from factory.

And yes it's the same style box and same filter as the base cobalts.

 

update from my dealer;
so around 9:30 this morning my dealer called and woke me up asking for my vin. I told him I would get it to him in a little bit as I didn't have it on me because I was sleeping. So I just called him back fully awake and gave him my vin. I had ordered the upgrade kit like ten days ago. My dealer now tells me that the part isn't out yet (duhhhh) however I am able to preorder it because GM considers it an accessory and not a performance upgrade (whatever, just gimme). He needed my vin to "spec order" it. He stated that there were 7 othre dealerships who have also preordered this item. And now for the only real piece of news. The parts guy told me that GM was going to start shipping these as of the first week of April. The first week of April. April.

fly your BS flags now. I am getting this from a parts guy named Shawn P....(last name was like pozlowski or something) at Criswell Chevrolet in Germantown, MD.

I also asked him about what the specs would be for performance output and what parts exactly should come with it. He stated he would call GM tech to try and get me an answer.

Take this for what it is. A parts guy trying his best to give me updates.

 

Just because it has the same filter and the box is the same does not mean it is the same intake system...I'd bet that the cone on the end and the piping is different size...

So you think that GM spent all the time and money to tune the SS/TC at the Ring and decided to restrict the air intake just for fun? Come on...

 

Yes I do. Same reason they restricted the tune. Same reason they restrict the SS/SC to a a 3.2" pulley.

They slapped cheap parts on there to help sell more Upgrade kits.

They knew the car could make 300WHP from the factory but they restricted the car for warranty and to sell more upgrades.

 

I just checked the K&N site and the 2.0/2.2/2.4 all use the same air filter. It's a tiny postage stamp sized panel filter. The LNF makes as much power as my 4.6L 3V V8 in the Mustang GT.

 

So why would they do that by putting a restrictive air box on it?

It is funny how they did just fine on the other LNF applications only selling the sensors and tune...they can detune it to whatever they want without intentionally restricting the air flow to cut down on performance.

You don't think they would have rather run a few seconds faster at the Ring and sold more SS/TC than selling less and selling a small performance upgrade?

This is one of the few SS's GM has done right recently and they put an excellent product out there...stop saying the intentionally put bad parts on it just to sell more performance kits...after all...this would lead more people to go after market and not even buy their performance kits....

 

Fact is they can't sell a loud car from the factory. They have to use a restrictive intake and exhaust to quiet the car down. The reason the SS does so well at the ring is handling not power. Hell the Camaro SS has twice the power and can barely do as well.

 

FYI, the turbo does actually use a different filter than the 2.2/2.4. Its a different part number and if you look at it, it says something to the effect of "for turbo"

 

It still has a very decent 260hp/tq on a stock airbox... for stock, it's not too bad.

It'll just make an intake swap a good upgrade for those who don't mind a CAI growl.

Personnaly I don't want the car to be any louder. So keeping the stock airbox and getting this car to 290hp/tq with that gm upgrade is fine by me.

 

It's the same. i compared the two. Same material shape and everything. It's a joke. A N/a ecotec gains about 5hp from a new intake. The turbos should gain 10-15hp.

 

Definitely the same filter; I got a K&N for mine, same part #.

Not sure you should expect that type of gain in a TC though... no diff, really.

 

Correct. I just put one on mine. Two comments on noise compliance. If Harley Davidson can get past the noise cops, STOCK, almost anything can pass. Did you know all automotive noise measurements are made from the CURB side. Just wanted to throw that in. Second point is the K&N filter DOES sound a lot better than stock, probably meaning it is flowing MUCH better than the stock filter. That's my 2 cents.

I stand corrected. The same filter is listed for the 2.2 also in 09. Didn't look any further. Sorry.

 

The turbo filter probably has more pleats or a slightly different paper material. The flow difference is maybe 50-100 CFM at most. I agree that if the N/A 2.2/2.4 are using the same airbox, then the LNF would benefit a great deal from a larger airbox and filter media - but I hope they don't use K&N style filter media. The cotton gauze crap has been shown to be inferior for filtration. I would NOT want excessive wear of my turbocharger vanes because of the K&N. The OEM's use a different fiber media for its forced induction and "cold air intakes" - if you look at the filter on the 08-09 Bullitt Mustang, it is not cotton gauze.

 

LNF filter P/N: 25894265
2.2/2.4 P/N: 21999324

Your "expert" comparison was not so accurate after all.

 

When i ordered mine, it was the same part #. I'll go with metroplex's theory that they have now made a different one for the TC.

 

As far as K&N filter application. The official word is theirfilter #33-2311 is used by, virtually, all Cobalt and G5 from 2005 to present. That number comes up when searching their site by VIN for application.

 

I meant the stock filter, not K&N filter.

I have the 2.2L filter in my LNF and it filts snug.

 

Those are GM part numbers. On my air filter, the one that came with the car, it specifically references it is for the turbo model. Of course they will all fit the same, the housing is the same, that doesn't mean the element is.

 

Hmm, looked the same, felt same, same shape and size as my stock 2.2L filter

Maybe ill do a comparison at O'Reilly or something.

 

See if you can get a specific part/calibration number for the cobalt... Thanks!

 

Boooooooorrrrrrrriiiiiiinnnnnggg, start a filter thread somewhere else

 

YES!!!!!
