Just found this so just want to share with everyone.


For BENZ C63 AMG, carbon fiber tubing gulps in cold air and is the best for heat insulation, which boosts the performance and driving dynamics, and drives higher horse power as well as torques. Even at low rotational speed, torques and horsepower won’t lose because of installing ARMA Performance Kit (must work with flow adjustable air filter). ARMA certainly will never abandon the stainless-steel air filter, which is reliable, stable, high filter capacity, of permanence and easy to clean and is the best guard against foreign bodies. For air filters of the same specification, ARMA also got ordinary air filters, which requires changing, and the ones without air-flow-control valves.

What's the deal with the little box?

 

I wonder how much it is

 

It seems lilke it has valve to close and open


Focusing on high quality, high efficiency and continuous innovation, ARMA keeps working on performance perfect as well as fuel efficiency. The ARMA HyperFlow Carbon Fiber Cold Air Intakes completely balances the performance and fuel-saving. The innovative adjustable inlet system takes account of both torques and fuel consumption at low-speed rotation. When it comes to high-speed rotation, it greatly increases the cold air flow to combustion chamber with the supercharging air-exchange system, and, within the shortest time, the hot air will be ventilated.

 

That looks really good

No price even on website?...really want to know how much.

 

Very interesting..........

 

It looks very cumbersome and overbearing. Although it may not affect it much, I feel like heat dissipation would be a problem with this intake. It could do without that center cover that's for sure.

And it looks cheap.

 

im pretty sure mb has alot more thought and engineering that went into the factory airbox over this terd.

 

Agreed. The cover on top will trap heat and residual heat after the motor is shutdown... Agree with the heat dissipation concern. Variable intake? does that mean airflow is controlled? Automatically/manually or not at all (I.e. Just a fancy name because the intake has a pseudo-Venturi design?).

 

Cost to benefit will probably kill you on this one. Variable filter? Dad's ram air intake is probably the best major intake mod.

 

Many have said our box top has too small of a volume due to the engine compartment restriction. Look at how large the SLS ones are.

 

True. If only MB made the hood/engine compartment slightly longer for the C63 we may have had larger air boxes.

On another note, if you're getting anything aftetmarket for the C63, just take a look at Renntech's products for comparison in terms of design. Their designs are tried and true; not to mention its owner help made AMG what it is today. I would go as far as to say their designs are the most optimum for our C63s.

Just my 0.02

 

All modern airboxes are designed to work as resonant systems, so the design itself, volume and tuning is indeed a rather complex process. I highly doubt that any aftermarket offering has gone through the trials and tribulations to just do the math, let alone tweak the design on an actual vehicle. It's not simply the airbox size or the air filter flow rate but rather how the low/high pressure pulses arrive at the intake port.

 

I have read the only aftermarket air box that makes a bit of power is the Renntech model.

I have one waiting to be installed. I plan on doing a baseline dyno just to see what / if it makes any power compared to the stock setup. Aftermarket air boxes for the most part does not do much in terms of creating power on our cars. Perhaps some more noise

 

As a different airbox would provide a different volume of air at different RPMs than the OEM one, you would ideally need to tune the car (the amount of fuel that is being delivered) for the particular airbox in order to get a noticeable benefit. You're changing the resonant frequency of the airbox (when you have the best air flow), and unless you can deliver more fuel at the new RPMs, you haven't accomplished much. I would be really interested to see before and after dyno comparisons - it would be great if you can get it done! And yes, the intake noise level will also change.

 

I would only assume that our MAF sensors will compensate for the additional airflow.

 

I don't know enough about the ECU in the C63 and what parameters it adjusts based on what changes in the various inputs it monitors, but it is unlikely that the stock ECU programming will produce additional power as a result.

While most ECUs will adjust the fuel trim based on throttle position, IAT, ECT and input from the O2 sensors, it is unlikely that the ECU will essentially learn a new fuel map by itself. The fuel maps are usually fixed and any significant deviation from what the ECU expects to see at a particular point would likely be interpreted as a malfunction and result in a CEL instead. Again, this is just a guess based on my experience with older-generation ECUs, but the fact that some of our cars have been known to throw a CEL for something as trivial as removing the carbon filter in the airbox would suggest that they are still largely operating in the same way. If for any given set of variables there is more air than the ECU expects to see, it will likely interpret it as a lean condition and throw a code instead of squirting in more gas.

 

Found price on it $2550 not including shipping

 

For that kind of coin, I'd rather get the Rtech.
