Default Cold air intake... Thoughts?

Went through a couple of intakes to figure it out, had to do some of my own work with the 90s and sensor input. Wondering if people are interested in buying something like this. Wondering what people think of it. I do feel a slight increase believe through the higher rpm's. I don't know if its the sound messing with me or what. I have a magnaflow exhaust with the sprint booster and this tank that I just filled up was 92 un-oxygenated, I cut the ports out from behind the grille and I feel like I can feel a difference. That box is definitely holding back some horsepower like X said when he had his dynoed with and without the engine cover on. Whether or not I'm getting true cold air isn't the factor. If you have ever driver for an hour sometimes a half and hour and felt the engine cover or even the tubes they are hotter then hell. This past week when I got home ready to work on this I couldn't even hang onto the engine cover it was so hot on the underside. Anyway let me know what you think...

I think you went from having two intakes to one. Why would you want just one?

There is only 1 intake manifold, not 2. Right now there are 2 inlets for air that go into the airbox that merge into 1.

But even still there's more air available for that one manifold to pull from. At least more surface area from having 2 filters.

Ok I have to ask this question. The two intake hoses that hook up to the front of the car are cold air intakes are they not? When you disconnect those and put the intake under the hood it seems to me you have converted your cold air intake to a hot air intake...or am I full of hot air?
Just wondering.

Like i said before have you ever felt your intake tubes or your air box do it one time and you will never call the duel tubes cold air intakes. Second they travel through restricted plastic air tubes in the grille to small air tubes up to the box through even smaller slits in the box to one opening. The AMG air box and the y port is about the only other option then this. HDDP has a twin system with a Y piece. I don't know just from putting it together and seeing everything as it came off there is no way that this is more restrictive. People are not feeling gains from the twin intakes off ebay because they are still going through the air box.

Not really since the airbox is only so big, it's not very free flowing unlike straight 3" pipes or 2 3" pipes. Even if the pipe holds less than the airbox, there is less restriction allowing more air to move into the manifold.

The quicker the air can get into the manifold the cooler it will be. Cold Air Intakes I would believe do not rely mainly on sucking in cooler air but moving air into manifold quicker like I stated so it does not heat up, think of cold Air as the location of the filter along with the amount of time the air stays in the pipe.

The only example I can think of is blowing on your hand. When you blow out through a smaller opening in your mouth producing faster airflow the air moving over it feels colder. Now when you blow out at a slow rate (with your mouth open more) it's hotter. Might not be the best example but it's the easiest way of picturing it.

I never thought of our system as a cold air intake. I call it a ram air system like the ones found on the Pontiac Ram Air Trans Ams. Our filters are located right over the engine and soak up all the heat. I'm also pretty sure those filters hold in a lot of that heat as well. If you notice on a cold air intake the actual filter is located outside of the engine bay or has a heat shield isolating it. The filter stays cool and the air simply blows on through into the engine.

Any OEM air filter system is going to be restrictive simply because there is internal baffling to keep the engine noise down, good for normal commuters, bad for performance.

It's 1 throttle body, not intake manifold.

The factory air box design was based on aesthetics (what looks good). Unless there are 2 separate throttle bodies there is no need for 2 air intake tubes.

Ok here is my .02
I know a little about cars so argue with me all you want.
The factory air box does two things.
1 filters air to keep debris from entering the motor.
2 Silence the air entering the intake manifold.
The problem with #2 is in order to reduce the noise associated with bringing the air into the motor baffles must be used. The baffles reduce air flow.
Now if you don't Mind "hearing" the intake there is power to be gained.
Two tubes are not necessary in this application.
The Mass. is just under 3" inside diameter.
One 3" intake tube will not have any noticeable restriction in it. "there are some rules here for bends and such but not enough here to make a significant difference."
As far as the hot air thing….
Yes colder more dense air from outside the engine bay is best.
The crossfire has limited space so behind the headlamp is the most logical spot and it is right behind the fresh air holes in the radiator support.
If you plan on driving you crossfire in all weather conditions you may want to refrain from running your filter down to the fog lamp area as there is danger of sucking up water. If you are building a “Race only” car this could be a good solution.
I hope this make some dense to you guys.
Oh also see here I found relocating the m.a.s.s. worked good for me.

I have a painted air box just like yours how much modification went into making it work second is it ever going to be able to be back to stock after doing that?

I didn't know that you can put two cold air intakes. Well maybe its possible to have more power since more air are sucked up. I may do this to my Mercedes cold air intake. Just a few mods i guess...

That is a "CLASS A" job... It looks terrific and you obviously spent some time getting the MAF sensor to attach properly...

I'm really not sure what you are trying to do here. Is this car for the street or track. I think you could have saved yourself a lot of time and money and just bought an SRT. Much easier in my opinion. If you are just trying to get the horsepower of an SRT, all I can say is good luck, but I doubt you can do it without some very serious cash. I know. I have been racing for over 30 years. Started drag racing motorcycles when I was 16, went uphill from that point. Sold my Top Comp car 3 years ago. So I too can argue horsepower and torque all day. When I read stryfox's post all I could do was grin. He pretty much hit the nail on the head.
All I want anymore is something reliable, quiet, easy on the eyes, and does .9G corners at the blink of an eye. That's not asking for much is it? LOL. After you turn 50 ya start to see things a little different...

Mercedes Cold Air Intake sucks up Air.

BWUHAHAHA !!!

I read this and I keep seeing that VW commercial where the ricer boy says that and then the buxom blonde in the lab coat says "Jah, it's definitely suckin'"

(((Thought))) If you want cold air, what if you set up your air conditioning to blow into the intake???

you would lose power driving the compressor ... more power than puffing a little cold air into the engine would give.

but it sure would be funny hahaha.
