For all you guys who are tired of Check Engine Lights, and worried about having problem with warranty from those oil coated performance filters. Well, you can order an AEM DryFlow filter and it'll fit inside the OEM air box!

Our 5" long filter with a 3.25" diameter opening will just push onto the intake like the OEM filter does, and the lid of the air box will hold it in place. I saw about a 5 hp gain alone with just the filter swap on the dyno.

The part # for the filter is 21-2110D with an MSRP of $53.69

Call up your local AEM dealer for availablility and accurate pricing.

I'll post up a dyno of a stock Cobalt SS and with just the filter installed.

 

What if we want to leave the bottom of the airbox off? Is there a bracket or anything that comes with it to hold the filter on then?

 

Wow That Sounds Really Good. And If This Is 5 Hp To The Wheels. Imall Over It. Considering Kn Onlly Gives U 7.

 

kinda weary, i mean i had bought the k&n and squeezed it in there, and put the box and everything back on, and it didnt do much, and it also made me have a cel, ill consider once i see more people buy them and their expereince's

 

Same here.... Im actually going outside right now to put my factory one back on... This CEL thing sucks

 

Will this also give those who like the hear the supercharger whine just that... the whine?

How much out the door with shipping? I know it may very upon region but I don't see it being more then $15 or less??

 

this is a dry filter , not oiled like the k&n , so you should not get a check engine light from it due to the MAF getting oiled


this looks to best the best option out currently

 

Ive been running AEMs dry flow filter for quite awhile now and its great....

 

Most of us who are running the Spectre or K&N filters with the AirBox Mod are gettting CEL's because of the engine leaning out... I don't remember the code but it's a lean code.. I guess it also happens with the factory setup and my dealer said there is a GM Bulletin up for it or somethin

 

oil from the filter gets on the MAF and messes up the MAF reading.

For the record I have had a K&N on my SS/SC for quite a few months now and no CEL from it.

 

Ive had mine done for about 1 month or so now and ive never had a problem with cel. I just have a 25 dollar cone from autozone

 

We don't sell direct to customers, and each dealer has their own price structure, based on what discount rate they are setup as. You can call any AEM dealer and give them that part number and they should be able to get you a price. I would guess the average street price for the filter alone would be around $40.

The filter will come with a hose clamp, so if you do take the airbox lid off, you will be able to tighten it around the filter neck.

Just putting the filter in the air box will not give more supercharger whine noise, as that will be controled by the box, not the filter.

 

Here are the dyno charts of just installing a DryFlow filter

 

damn that thing spikes alot between 2600-3000rpm. was there a possible issue with the run, or was it that way on multiple pulls?

 

nice dyno #s , both stock and with the filter

 

I think it has to do with noise cancellation. If you capture the data fast enough, the whole run looks like a sign wave. To counteract that, they use a noise reduction scheme in the software, but the peaks and valleys still show up occasionally. To really eliminate it you need to setup a speed sensor on the dyno and run a reverse sign wave thru the data based on the pickup on the dyno. Makes the data more accurate. We are working with Mustang to install that on our dyno, but we haven't gotten there yet.

And, also at the slower engine speeds, the car does tend to not like doing a 3rd gear pull from such low rpms. The drivetrain doesn't like it and the car will rock...which adds to the low speed bumpiness.

 

Also if you look at some dyno's they cut off anything before 2500 - 3000 rpm.

 

ah thanks for clearing that up roger... you clearly know too much for your own good :P

and yep you're right zinner. when i typed that, the fact it was sub 2500rpm, even though i was looking at it, didn't register right in my head lol

 

Is that me or there is a 9 HP increase and 8 ft-lb torque @ 5500 RPM ???

 

Hey Roger did the after dyno test have been made wit the lower cover removed ? What type of dyno ? 3th gear ?

 

No, the lower cover was reinstalled and the splash gaurd put back in place.

Yes, to be exact, its 8.5hp gain at 5500rpm.

Dyno pulls done in 3rd gear. In general, all 5-speeds are done in 3rd gear and 6-speeds are done in 4th gear.

 

Do you have a graph of the air fuel ratio ?

 

No, we aren't setup to log it for intake R&D runs. We have a hand held scanner in the car to observe during dyno runs to watch fuel trims, coolant temps, O2 sensor, etc....just to make sure it doesn't change too much from stock. We are mostly concerned with fuel trims and try not to deviate too much from what it does from the factory.

 

OK thanks for your fast answers, it's appreciated !

 

Hey Roger.....nice gains with just a filter. I was wondering when your intake AEM CAI will be available? I am still waiting for the K&N Typoon its supposed too be realeased Oct 3/05. Do you have any idea what sorta hp/tq numbers extra the intake would get above the Dry Flow filter with the stock intake? Colin
