Without hearing it myself, my first thought is that it is likely the re-circulation valves doing their job. They are working at times we as drivers don't expect them to, in order to modulate and regulate boost pressure. Our intake system (as you're already aware) open up the auditory notes of the induction sound which also means we hear more of the re-circulation valves. It makes sense at low throttle or at WOT you don't notice this since they are likely fully closed; but during medium throttle pulls they are working their magic (they seem to be very active on our cars and are constantly working based on ECU commands).
Hey thanks, appreciate the response. I think you are right that the diverter valves play a much more active role with our engines then I have seen on others. I do not necessarily think this is a problem, will keep an eye on it.
I’m running stock software at the moment and I can absolutely feel the difference. Stock software does not taper off HP to redline like a tune with stock turbos, so to me that linear powerband and the extra puff up top with the intake installed really wakes up the car - especially the top of 3rd/4th, where you’re spending more time above 5k rpms.
Yes you can just zip tie them back or hang them out of the way somewhere. Just remember to remove the sensor from the factory Box and plug it in to the harness so you don't get a code.

what do you mean ?? I pulled my sensors (map) one on each side, and there is nothing to plug then back into ???
you just zip tie then down (to harness is fine)
but what are you referring to that needs to be plugged in ??
We got a few sets of filters in today and currently have 2 complete intake systems in stock. With the purchase of an intake we will throw in a turbo blanket 1/2 off with promo code HalfOffBlanket.

I finally got it installed today. I had some problem installing air filter to carbon intake tube myself as filter kept slipping off while trying to tighten the clamp.
I had to call another person to hold both intake tube and air filter together while I tighten down the clamp. Other than, installation was pretty straight forward.
Like everyone mentioned, I definitely noticed more top end power even on stock tune.
It’s gonna take few more driving for me to get used to those additional induction noise.

Thats AWESOME... yea I love the sound as well... I have Renntech BOV's as well, so on aggressive driving, there are lots of sounds going on...
I made a mistake of over-tightening air filter clamp when re-installing intake and it ended up putting a deep cut on the filter flange.
I was looking to purchase replacement air filter (aFe 21-91122), but pretty much every place including ModalWorks and aFe had nothing in stock for a month or so.
After looking at multiple performance filter company, I realized that it was impossible to find exactly same size filter that comes with ModalWorks intake.
However, I found dry flow filter from AEM that is 2 inch shorter in height but has slight larger top and bottom diameter compare to aFe filter.
I ordered these filters from Amazon and with help of 0.25 inch width O-ring (because inner flange length of AEM filter was only 0.75 inch vs. 1 inch from aFe filter), I made it fit perfect and tight inside box.
Other thing I added to it was pre-filter which provides protection against dust and liquid for peace of mind.
Quick test drive shows no noticeable performance decrease vs. longer aFe filter, and no reduction of intake noise. Actually, I feel like noise is slightly louder with shorter AEM filter for some reason.
Anyway, just posting this for information purpose. It may be helpful for those who live in desert area or drive during heavy rain season.
Here is pic of ModalWorks intake system installed with AEM filter + pre-filter.
I also want to mention that ModalWorks customer service is exceptional.
I lost few screws due to my mistake, yet ModalWorks sent me those replacement screws free of charge!
Which of these would be better and why?
Are they both easily serviced vs. replacing at intervals?
New to the forum, just picked up a 2019 GLC63s, Actually has not been delivered yet (due today)
Only 7K miles, looking forward to Driving it!!
I like dry filter. It is easier to maintain and there is zero chance of messing up any sensors.
I think performance difference between oiled vs dry is pretty negligible.
It's been over a year since we have bumped this thread and in that time we have had tons of customers adding more horsepower to their vehicles, one exciting example is from a set that was installed last week on a stock turbo C63.
A customer provided dyno and dragy data showing 70whp gain. They also backed this up with back to back dragy runs showing a 0.41s improvement. The only difference between the dyno and dragy are the change in intake. Our intakes consistently produce the most power and were used on the current world record 1/4 mile W205 C63. Data doesn't lie and we are pleased to see many other are matching and exceeding our initial claims.
