ModalWorks has finalized the design of the intake system for the W205/C205 C63. This is an easy to install bolt on mod that adds over 57whp and 45wlb-ft to stage2 models. Images shown below are prototype units and production units are currently underway! Production units will be made from carbon fiber tubes with high quality powder coated heat shields. Pre-ordering is live and available for the next two weeks. Order now to lock in the $800 price with only $400 due now: https://modal.works/shop/highflowintake
We have done extensive analysis and testing on this intake system. CFD models of the air intake were performed to optimize flow paths. Our results show that with properly designed heat shields, the concerns of a “hot air intake” are mitigated. Our design uses 3 layers of protection to reduce warm air that would normally enter the intake with an unsealed heat shield. These heat shields are constructed from stainless steel, finished with powder coated, then covered with a heat barrier made up of woven silica with an aluminized finish. The shields then have a gasket added that seals against the hood that reduces hot air transfer from the engine bay to the intake. Side by side comparisons of stock vs ModalWorks intake show negligible differences of air intake temperatures pre-turbo, which result in big performance gains due to massive improvements in airflow.
Dyno Results:
Back to back dyno runs were performed swapping the stock intake (with aftermarket high flow filters) and the ModalWorks intake systems. The ModalWorks intake showed peak gains of 57whp and 45wtrq higher than OEM. Comparing the absolute max power generates for each, the ModalWorks design gained 25whp at 5500RPM.
1/4 mile and 60-130mph:
Dyno numbers are one thing but putting that power to the road is where it really matters. 60-130mph and 1/4 mile tests were conducted back to back. In order to reduce the number of variables, all runs were done in S+ mode, sport traction, with all shifting left to the vehicle. All tests were done on the same stretch of road, same day with the same weather. Comparing the best runs for each intake, we obtained a 0.42s quicker 60-130mph, reduced 1/4 mile times by 0.14s, and improved trap speeds by 1.5mph, all from just an intake.
With driver selected shifts points on a properly prepped track we expect even better times. More testing needs to be done but this is a snapshot in time of the current progress. * Note: Average results are the top two fastest times averaged.

I guess numbers don't lie but I can quite understand why your intake would give almost 2x the power gains of any other competitor (closed or sealed designs alike)? Almost too good to be true to gain 57whp at max RPM and 25whp at peak with just an intake?! So you engineered so much better than any of the other, experienced performance tuning companies out there?

Thanks for all the interest. The 57whp gain is really high in the RPM band, where the stock intake plumbing is choked. As a reminder, these runs were performed with Velos stage2 tune with our high flow catless downpipes running on 93oct.
We spent a lot of time on this design, created numerous iterations with prototyping and testing, and backed all of it with computational fluid dynamics (CFD) simulation to get the intake shape optimized and really improve flow. If you really dig into the OEM design, you will find it is actually not optimized for power levels significantly above stock.
As you can see, the performance gains of the ModalWorks design is truly realized on the street with significantly improved 60-130mph and quarter mile times. We strive to be transparent with everything we release and want to offer an amazing product to the C63 community.
Do you have a photo of a carbon fiber version. Or a photo of what the final version will look like exactly?thanks
Right now the production tooling is underway and we will have the first samples in house within the next 4-6 weeks. You can check out more renders on our product page here: https://modal.works/shop/w205-c63-hi...ntake-preorder

so to clarify: 57whp on top of a standard high flow filter but Velos stage 2 and downpipes...?
I like it because it a sealed box. To even get more cold air in, I would cut the lengths of the airbox side hood gasket/seal. You can always install the seal back anytime.

Yes, everything presented in the post above is with a Velos Stage 2 with our catless downpipes. Dyno testing compared an OEM airbox with high flow filters. I have some results comparing OEM with stock filters and OEM with high flow filters that show there is a negligible difference in performance.
These will drop right into the GLC63, but the heat shield design as it stands is optimized for the C63. We plan to explore optimizing the heat shield specifically for the GLC in the coming weeks.
What happens to the factory IAT sensor with the intakes installed? Is there a provision for that?
The sensors on the OEM air boxes are not IAT, but are vacuum sensors used to measure when paper filters need to be changed. Our design does not utilize this feature... the sensors remain plugged in and are tied back to the surrounding cable harnesses. This is a similar approach to other manufacturers and does not cause a CEL.
HP numbers appear high but if you look at the dyno curve it is essentially makes more peak power then stays pretty flat until redline, where the stock intake tapers off. Our intake geometry is no longer choking the flow due to an optimized airflow path, and it reduces the pressure loss the OEM intake incurs.
Carbon fiber is currently the only option we offer. You can pre-order for $400 now, and $400 due before shipping for a total of $800. Retail prices after the initial pre-order special will be $1100 total.
We'll also have more videos soon! It really sounds fantastic and you can definitely hear all the spools and re-circulation action.
Hello, I’m interested. How’s the install? Simple steps, simple directions? Is the hardware stainless steel? Had several of the K&N kits in the past and the hardware would rust.
thanks for the info in advance.
Of all the intakes out there, this one checks all the boxes (with price being a major factor). I do have a question though with your data. Why were the dyno pulls only to 6500 rpm? I really want to see what happens in those last 500 rpm to the 7k redline. I'm currently running a Dinan tune and I find that if I shift at 6500 (before the turbos choke out) I get better acceleration on the top end in higher gears.
With this intake, do you still get gains running it to the 7k RPM redline, or would you recommend shifting at 6500 rpm for the best acceleration on stock turbos (despite the HP increase on the top end)?
I currently have Velos Stage 2 and catless downpipes but I feel like the car falls flat on its *** after 5500 rpm or so. I wonder if the intake will fix this.
It's the turbo's they have small turbines
Would need larger turbo's for more top end performance in the higher revs
Ugghh that sucks but I thought that would be the answer. im looking into getting the pure 800 turbos but I'm trying to see who I can get to tune it. Velos told me they don't tune for turbo upgrades and I've heard a few bad things about others.

Talk to the guys at Weistec and Renntech - both offer upgraded turbos with tunes....I think both also recommend to upgrade other components to withstand the extra load (transmission kit etc).

I'll reach out to them see what they offer. I'm hoping to try and get something done by the end of the year when I can take a couple of weeks off work.
Thanks
