i have been using K&N filters in every car,truck and Atv that i have ever owned and i have never ever had a problem with them .. if your not retarded and follow the instructions how to properly oil them they are a much better air filter they flow a thousand times better and they last forever...

 

Cleaning them takes too much of my time. My paper air filters usually last about 4-5 years before I throw them out. If each paper filter is about $5-$10, it's not worth my time to buy the K&N and rely on the tack oil. We've used nothing but paper filters for over 30 years and never had a problem with any of the engines. Yes, K&N flows better but only because of the minimal pleating, thin depth, and large holes in the cotton gauze. In addition, the "1000 cfm" is useless when your airbox is the restriction, or if the air intake tube is the restriction. In almost every OEM application, the air filter is not the restriction.

 

this thread is full of ******* retardes the airfilter is the same at the 2.2 and 2.4 just order one of those

 

Please stop telling people here wrong information. They are not the same filter. The turbo filter is reinforced with extra ribbing on the filter to prevent the turbo from sucking it in.

The 2.0 turbo AC Delco part number is A3106C. The 2.2 part number is A2956C.

How do I know the difference between the two? Because I pulled the filter out of mine and my girlfriend's 2.2 and compared them. They are, without question, different.

 

I like my K&N... I didn't realize the turbo uses a different filter than the rest, its the same filter, just with plastic glued to it to keep it from flexing??? WTH?

 

Your an idiot I have the 2.2 k&n in my car and it is not ******* psyically possible to get the air filter sucked into that small of piping you are a complete idiot if you think that's possible

 

BTW... a K&N oiled filter is simply better becuase it will last the life of your car if properly taken care of. (cleaned and re-oiled during regular maintenance)

the only time I have heard of someone messing up the MAF sensor was when putting WAYYYYYY to much oil on and not letting it sit for a bit after.

 

4-5 years?!?!?! So you are saying you drive 2000 miles a year? There is nothing wrong with K&N filters so stop bashing them. They make a great product that works. And yes the airbox and intake piping is where most of the restriction is. Drop in filters are almost useless in for getting alot of power. But the round conical filters on the cold air intakes are useful and do flow alot of air.

Yeah and CRC make something called "MAF Sensor cleaner".

 

agreed 100%


lol 4-5 years before replacing a paper filter

 

I've used K&N in everything. Never had a problem. Got rid of my last car kind of early but the two before that had over 150K miles (before I sold them and they were still running great). No internal engine problems ever.

Oh, and the K&N for the Cobalt? I just walked into Autozone and there it sat on the shelf.

 

Your an inferior human being.

 

With respect, we've done testing in our labs and K&N filters don't filter as well as paper. It's a proven fact, just do a search to find public domain results like the one on BITOG:

Whether your car "runs fine" or your Eclipse/Talon turbo ran fine with K&N is not being questioned. The OEMs do not use K&N filters on the majority of performance production vehicles backed with a full powertrain warranty (someone used the Ariel Atom as an example, and that is a VERY low volume specialty track vehicle, not something that would be used by Joe Sixpack driven in the dust bowl area for 100,000 miles).

The GT500 uses a paper panel filter. Ford's factory conical cold air intake even uses a cellulose/fiber media (Bullitt CAI kit, 2010-up GTs). The OEMs do severe testing in all environments, including dusty areas and in the desert. The K&N filters just don't filter as well as paper. I guess I want the cleanest air going into my engine. I don't feel like sacrificing filtration efficiency for a few cfm of air flow especially when I have an expensive turbocharger in the plumbing.

Yes, I would throw out a paper filter every 4-5 years depending on my mileage. I split my annual mileage between several cars, depending on which one I feel like driving. There's no benefit for me to even consider a K&N for cost savings since it wouldn't save me much money. The dirtier the paper filter, the better it filters. I have several K&N's and Fram AirHogs sitting around on my shelf. They were either given to me by friends or they were free after rebates. I think the few AirHogs I have were free after rebates and I even earned a few bucks in the process.

Just around a decade ago, I experimented with Accel's KoolBlue air filter (oiled cotton gauze) on my 2000 Crown Vic. After extensive airflow testing, I observed about a 5-25% improvement in airflow at 3000-5000 RPM which translated to zero gains at the track. The benefit that most people get from running K&N cold air intakes is the larger surface area and lower restriction from the lack of an airbox. The K&N stock replacement filters are worthless for power gains unless your original paper filter was severely undersized for the application.

There are some public domain studies on K&N filters like this one as well as the BITOG test I mentioned before:
http://web.archive.org/web/200607042...011/SPICER.htm

The bottom line, and this is a proven fact whether you agree or not, is that K&N style filters do NOT filter as well as paper filters. Whether a race car driver uses nothing but K&N filters is not even remotely valid as an argument for using K&N because we don't do teardowns of our engine after one 1/4 mile race or after 500 laps. We don't drive on well conditioned race tracks. We may encounter sandstorms, excessive dust from industrial or construction areas, etc... and I am not sacrificing engine/turbo longevity to squeeze out an extra 0.05 hp.

 

Well this guy doesnt want to wait weeks for the stock paper filter but there is a K&N sitting on the shelf of a pep boys. So the K&Ns dont filter as well. WOAH BIG DEAL its not like its going to blow up your engine. Why did you buy an 09 SS anyway? Church and groceries?

 

Your maturity level is impressive. Are you 3 or 4 years old?

The shape of the filters are the same. A K&N is reinforced with steel mesh to prevent the cotton from being sucked out normally and won't have a problem. That's why you can use the same K&N for the turbo.

The 2.2 OEM filter is not that strong, flimsy even. It it certainly possible for the turbo to suck the filter out of place and while it will most likely not get sucked into the turbo, it will let dirt into the engine. That is why the OEM for the turbo has reinforced ribs.

Obviously you lack the brains and common sense to be able to understand such a simple concept. It's too bad you weren't half as smart as you think you are.

 

I use the Crown Vic for church and groceries.

 

you got me you sly guy haha I'm completely and utterly stupid and yet my car Is how much faster than yours?

 

Why do you say this. Because of the oil?

 

So, you're bragging about your modded car being faster than my stock one. How impressive. Everyone please join me in applauding him. Well done.

When my life becomes so utterly pathetic that I have to come to an online forum and act like a 3 year old name calling and bragging about my car being fast, I'll quit driving and walk.

 

I have used K&N's on all my simpler cars. Monte SS, Mustang GT, ans presently on my Turbo Regal. I assumed I would pop one in the Cobalt in a month or two, but this thread is giving me second thoughts. This the first time I have had a car (Car for Power) that was untested. All my other cars, I knew that whatever I did, some one before me did it, and lived through it.(Except maybe my bizarre meth injection on my Buick) I am leaning toward paper, and another year before I pull out the zip ties and sawsall. Also, if the computer adjusted for what ever CFM improvements, will it do a damn thing anyway?

 

Im selling an air filter...for a 2.2...just check out my thread...I could ship to Canada..

 

LOL... I was gonna say the exact same thing!

I did not notice any power gains with the K&N over the stock, but the turbo spooling up does sounds louder!

 

The cotton gauze material does not offer better filtration than the paper filter media. The K&N-style filter relies on the tack oil, which doesn't do nearly as good of a job as the paper filter. So in terms of filtration, the paper filter is better.

Besides the reduced filtration efficiency, I have yet to find a K&N filter that didn't have numerous defects in the polyurethane sealing material. There are always a number of air holes and pockets, sometimes leading to massive holes in between the media and seal, allowing dirt to bypass the filter media entirely. I had K&N replace one in the past but I never bothered to use the new replacement.

 

With the SS/TC you need to tune it to make any more power with mods. Just like VW's. There is nothing wrong with using a k&n filter and dont let some old fogey toolbag on here make you think otherwise.

 

Sorry for the thread jack but notice how no one agrees with you because the people that know me know that all of the cocky comments I make are sarcastic so you just made yourself look like a *******

 

So now you were just being sarcastic and I'm a *******? So be it.

The fact remains that you gave another CobaltSS member incorrect advice about air filters that could have potentially damaged his car.

Who was the ******* again?
