Airbox from OEMPARTSDIRECT arrived about 5 days after placing the order. I live in PR so it takes awhile. Paid $419 for the set-up and all looks good. Just got my green filters ($100) today so i will be installing tomorrow for the road test. keep you posted on how it performs...

ok...so i couldn't dyno the car before and after which is the best bet. I did the next best thing...my friend has a G35 coupe and we did some racing before and after just to test any difference.
Airbox gives you a lillte more roar from the motor and racing results prior to airbox we would remain side to side after airbox half a cars length after about 40 mph.
Mod approved!

Guys, help me out here, no matter which airbox you use, seems to me to make no difference. It's not the airbox that matters ,it's the amount of air taken in verses the amount of exhaust you get rid of. You can mount a OX tank on the hood and feed it all the air you want but if you don't change the exhaust volume, what has changed? also the amount of air coming in is limited by the size of the intake scoops at the sides of the radiator, no one has mentioned increasing the size of those. If the filters are the same size green/stock, the difference is only min . I actually do have a green filter on my C class, but bought it because it's reusable not for hp gains. The O2 sensor reads the air/fuel mix and keeps it at factory presets, so where are these 25hp coming from? maybe some of you mechanical engeneers can help ?

I'm working on a DIY section for my website and it’ll have ramblings about airflow. Hopefully that will be of some help. If nothing else I'll be able to cut back on the all night emails responses about how cars work. Anyway, airflow . . . . . . . . let's think about this, a normally aspirated 4.3 liter, spinning at 6000 RPM, at 100% volumetric efficiency (which we'll never come close to seeing), can only flow 455 CFM. Do you think there’s an exhaust impediment that limits flow below 400 CFM?
Lastly, O2 sensors are not used at WOT.

Josh K did a before and after dyno and the *only* thing he changed was the airbox. There was a difference in the dyno number.

Is the log style manifold that has exhaust pulses banging off the back wall a problem? Definitely. Is the 90˚ bend in the exhaust tubing a problem? Absolutely. The low pressure zone created by the resonator? It could be better. The low pressure zones created by the cats are minimal and unavoidable (unavoidable if one wants to pass smog in the land of fruits and nuts). The size of the stock tubing? On a non-boosted 262 CI engine that doesn’t see more than 6K RPMs, hollow 2.5" exhaust tubing isn't the problem. Going bigger *may* produce a bigger peak dyno number. However, the problem with going too big is the velocity will fall through the floor, killing any semblance of scavenging along the way. Without midrange scavenging, the dyno will show lower numbers below peak, and the qtr mile trap speed will drop.
Have I got it all wrong? Possibly. But I'm in good company. The GM powertrain engineers think 3" ID tubing is good for the z06, but that engine is over 60% larger and revs to 7K. I know enough about air flow to know that my theoretical blathering about what sized tubing is OK can ONLY be proven using dyno numbers and backing those numbers up with trap speeds.
Going back to benzover's question, I don't *think* the exhaust is strained to the point where the AMG air cleaner assembly doesn't make a difference. Josh K's dyno numbers reinforce my opinion in this area.

1) past the hoses to the filters (less turbulence)
2) through the filters b/c it will allow a higher flow rate
3) and maybe (havent looked closely) from the filters to the manifold.
4) making this flow go through faster leaves slightly less time for the air to get heated up by the engine as well.
So as you see, the 2 challenges after the intake hoses are shape for direct flow and high CFM filters. Turbelent flow isn't terrible because it will enhance your gas mileage. However, the laminar (or normal) flow is better for volumetric intake and HP.

Lol funny wut my thread turned into....all I know is that I felt a somewhat notable difference when I put in the amg box wit green filters....so for me...it was worth that 500 or so I spent for the minimal hp gain esp wen its so hard ta get significant numbers outa car without spendin thousands....
Devilsangel....I went with green cuz of the good things and gains that I've heard others gettin from usin them n also cuz I herd that many ppl who tried the k&n's ran into MAF issues after cleanin/reoiling....

Ok that works! I'll definitely give the green filters a chance. Thanks for the info.

Wow, I thought moving from Toyota forums to Merceds would introduce me to perhaps a more mature group. Apparently not. The Jury has some serious confidence issues to have to post pics of something completely unrelated to the thread to help boost his ego.
Making fun of someone's out of producting car and then flaunting an old *** car is probably not the smartest thing to do. A nice house and nice car, but unattractive personality is so sad. I hope he pulls his head out of his *** soon and joins the rest of the mature folks here who can have a normal conversation without all the craziness.
I wish people like The Jury would either change for the better or completely get off the forum and leave this place for the normal people to speak amongst themselves without their insanity messing up the forum.
Good night.

Guys, is this any different from the guy selling the Carbon Fiber Airbox here for $1,500? I believe that the hp gains claimed are about the same.
