Dual Cone Intake
I've noted that many for sale specify 97-00...is this a universal item that can be used on a 2004?
Is a hood seal required?
Also noted that some are aluminum or chrome, or are they all the same?
Finally, any recommendations on a reliable ebay vendor?

I think the difference in 97-00 and the 01 to 04 is the location of the Air sensor. The newer ones (like your 04) have the sensor built into the MAF. The older ones had a seperate plug that had to plugged into the intake tubing.
Hood seal isn't required and probably doesn't help a lot but can't really hurt either.
You will find lots of different styles (chrome, black, larger diameter, etc.). I've heard some people argue against the dual cone ones saying that the airflow isn't as smooth going into the intake because it is coming from two different sides (as opposed to a Blackwing for instance where everything is funneled through one aircleaner). Not sure if there is any meritt to this argument or not.
Can't help you with any Ebay vendors (don't really know any for that type product). But there are some really good forum vendors that provide tremendous customer service that can probably help you out too.

The size of the neck that you hook it up to is a different size on the earlier cars than the later models. The area right in front of the MAF. I'm suffering from CRS and can't remember what it's called!

Yea...I'm suffering from all the Cfill in the blankS'.
I'm hearing hood seal is required so that you don't saturate the cones with water...any truth to that?
Those that look like chrome...are they just polished aluminum?

FWIW.... I ran one of these twin cone deals and it made my car (2000 vet) run waaaaaaaaayyyyyyy lean. On the dyno it ran at 17.9 to 1. Crazy lean. With my predator we were able to tune it to 15 to 1, but still... So I took the thing off, and after warning him, one of my friends wanted it real bad, so I sold it to him and his car started throwing lean codes immediately. I haven't had the chance to retest my car on the dyno with the factory airbox, but I have to assume that the intake made it lean. My tuner thinks it's the way it makes the air swirl as it passes the MAF.
I aint no expurt, but I won't run that style intake again. Just a free warning from my experience with no concrete data.

That's interesting... I wonder if people have gone lean using other intakes too. I recently installed a Blackwing and have no issues (so far). I was looking at the dual cone intake too (looks cool) but I didn't think it was as effective as the Blackwing since the tubes curve to the sides.

When I bought my car, the previous owner had installed the RM brand twin cone intake. I didn't notice any performance issues with it. I discovered the Blackwing, a buddy gave me one that he never bothered to install - and I have never looked back.
I did notice slightly better throttle response - maybe I'm imagining it because I want to believe that it is an improvement. But I do know that the Blackwing filtering media is the best from the perspective of filtering out smaller particles of dirt compared to the OEM paper filter or the cotton cloth of the K&N - which is typically what you find on the twin cone type filters.
Neither the Blackwing or the twin cone is considered a cold air intake. If you want a measurable performance improvement, look at the Callaway Honker and the Vararam.
As far as the hood seal - I have one, and it is most effective at keeping the water and dirt from entering at the front of the hood. Beyond that - regardless of the wild claims, the hood seal will not give you any performance improvement (though I did net at least 20HP after I installed mine!

Personally, I'm running a Blackwing with drilled foglight shrouds, but while at Vettes on the Rockies a couple of weeks ago, I got to talking to the fellow from Dragon Engineering. He had several blown cars there in the 900-1000 horsepower range and they all had the dual cone intake on them. They must not be too bad.

^^^^Good to know. I picked up my dual cone for cheap from a fellow forum member. I'm gonna keep running mine for a while. Again, I've never had any problems with mine and I like the way it looks under the hood!

I ran a BOMZ twin cone on my car because it was cheap and i liked the way it looked. It also made a cool sucking noise when feathering the throttle. I replaced it with a used Blackwing I picked up on an auction site for $125. The best thing I ever did. The Blackwing may not be as pretty under the hood, but it woke the car up significantly.
Throttle response was no comparison and my wife and I both noticed a HUGE seat of the pants feel after the swap.
Don't buy the dual cone. It's a waste of money. Shop around for a used Vararam or Blackwing if money is a concern.
I would have given you my old BOMZ with the filters, but I already gave it away.

Hi There blacksedan87,
I was interested in knowing what other mods you have on your car?
I 'am considering installing the black wing a/intake & a z06 air box. My 01 vette is completely stock.Will the increase in air flow cause MAF sensor to display any lean codes?Any lean bank codes?(air/fuel mixture)
I don't plan on any other performance mods.
Thanks for your advice.

You modify the engine mechanically to increase airflow potential through it.
You modify the PCM tuning to add the additional fuel to support that increased airflow.
If you add air, but don't add fuel...yes, you will run leaner.
Fuel trims compensate for this well enough to accommodate bolt-on items. like air filter and headers, so I'd tend to believe you had more of a mechanical issue at fault, or a bad WB02 reading to run as lean as you claim, or you simply didn't wait long enough to let the LTFTs settle in and compensate..
In closed loop, the PCM will always adjust fuel trims in attempt to keep you at the 14.7 stoich setting. If it doesn't seem to do that, and throws no lean codes, your afr measuring equipment would be suspect.

i agree with the above info about the different year groups. imho unless you're getting the dual cone intake for the look, which i can understand, id get an intake that doesnt take air from the engine bay, ie vortex rammer, callaway honker, vararam, etc. Just my .02. Good Luck
