Best Air Filter, AirBox, Air Intake
I see a lot of people on here have ROW airboxes, AFE filters, carbon fiber intake etc.
I was wondering what the best combination would be from all your experiences? Any combination that will give the engine better sound quality?
Another thread on here somewhere asked if the K&N filter were the same as the Weistec or AFE...
The difference is really that K&N oils theirs, take that red oil off and the filters look identical. I wouldn't be surprised if K&N manufactures for the other guys and stamps their names on the product for resale.
Regardless, I am running K&N's but feel there is no difference in filters.
Where the debate really lies is in the intake system.
Many have claimed hp gins from the CF style intakes, those claims are typically shot down pretty quickly by consumers leaving vendors struggling to stand behind their products proving otherwise. Most agree that the gain from these intakes is from the upgraded filter while installing the CF style intake.
I am currently running the ROW's with K&N's that is an automatic charcoal filter delete. I personally don't think my butt dyno is tuned well enough to pick up on any of the gains, if any are present, but I am happy with the products I have installed. I have not received any CEL's thus far and it has changed the sound in a positive manner according to my taste.
Hope this helps in some way. A lot of non-proven facts in and around this topic. My guess is AMG built an incredible intake system that is more than sufficient for the 156 and is hard to top. I would be willing to bet installing filters is all you need to do to squeeze a few more unnoticeable hp out of the car.

ok ok, abcut973 is a baller as well, confused myself as you (abcut973) have the Renntech tune, not intake.
FYI I just did the V5 tune I put down 440 WHP and 380 WTQ. (Read: 525 HP and 460 FT TQ at the crank) with my bolt on's. This is also on a low reading Dyno Dynamics machine, on Dynojets you can add 8-10% more HP. Dyno file attached.

My baseline on the Eurocharged Dyno was 390 WHP and 355ish TQ prior to uploading the V5 file.
So a net gain of 50WHP and 25TQ. Take a look at the dyno sheet and you will see the gains from the baseline.
This is why Dyno's shouldn't be taken as an end all. They all read differently. But im confident in the Eurocharge Dyno reading. From what I understand Eurocharged Canada stated its one of if not the most powerful C63 they have tuned without headers.
With headers I'm sure I can surpass 500 WHP and 420 TQ.

Has anyone in the C63 world constructed something like this? It should be pretty straightforward to fab this up - just a "Y", and two bends of 3" pipe. And there should be pretty significant gains as well.

MAF sensors and ecu control the amount of air going into the engine, constantly regulating it. If you increase the amount of air flow available without a tune, why would you expect a performance gain? It will only suck what the computer tells it to suck regardless of how much it COULD suck.
What am I missing here?

ECU or "Computer" - The ECU is similar to that of a brain in the human body. Yes it tells the rest of the car how to operate, but if the pathway is restricted, or not working to its fullest potential, it leaves room for improvement. By improving the amount of air that can be introduced to the system and the easier that air is obtained, the better. The brain is only telling the system when to breathe and as long as the MAF isn't finding TOO much air, then the system should accept the amount being introduced. If the filter flows more freely, then more air should be inhaled as the car isn't working any harder to gain restricted air than it is to inhale more flowable air. It will always inhale at the same rate...
Not sure if this is 100% accurate, but this is how I understand it.
the primary input is your foot though
filter/intakes can provide marginal gains by lowering pumping losses
for a given rate of acceleration you need X torque
to produce that torque some is lost as parasitic losses, one of which is pumping air through the engine...if the intake restriction is lowered, ie, filter DP, those losses are smaller...so more net power available for accel, or reduced throttle position for the same accel
this can improve efficiency a bit also under normal operation

picked up 7-8 HP as dyno proven by European Car magazine
picked up 1 mpg average
a little more noise
saved some money cleaning vs new paper
some environmental benefit: less crap in landfills
but I agree, no big power gains and stock is more than adequate
Spend the money on a proper exhaust system/headers and supercharger instead.
So I guess I'm wondering what the spectrum is on HP/tq gains for more modest to more widespread exhaust mods? Thanks for the input
