I see you're a fairly new user just registering, all of you concerns have been answered in the past and the answers can be found throughout this forum. I'd strongly suggest searching and you will most likely answer every question you have asked/will ask!
To chime in though, the MDesign intake uses the OEM intake air inlet just as the OEM system does and the probability of water entering the intake is just as likely with the OEM intake. The OEM intake has no drains, it is a sealed unit just as all (if not all then most) OEM manufacturers intakes are designed and MDesign intake is designed. Furthermore, there are a number of vehicles with the intake along with the intake on my own personal vehicle for over 40,000 miles through floods, heavy rain, and snow with no issues.

^^ This 100%. The engineers at Ford knew what they were doing when they placed the inlet tucked in behind the grill and up against the hood.
Being a new user, you should know I don't know all the threads out there. I was responding to the present post and asking questions about the setup.MDesign said:
A suggestion for you being a seasoned Forum go-er, update your FAQ on your website to answer all these questions and people can do the proper research instead of asking questions
Thanks for the response.

I think a few of us had the same, legit, concerns. And the search function isnt all that great here. Thanks for taking the time to answer....MDesign said:
Have you had this particular intake for 40,000 miles? Just curious as to how long this has been out. I thought it was fairly new.
Water... might be possible, but short of immersing the car I am unable to get water to my underhood anything or in the intake of the CAI with prolonged and extensive 3100PSI PW weekly since I got one of the first 5 MDesign CAIs built. Several driving rainstorms and we had our 100year flood due to some of them... Water won't get in... the intake was well designed... mine has been on my car since build date 9/13... even says dry when I PW the engine.. Testing... always happy to read and don't discount any offhand.
Yeah, the search is context sensitive that way. If you want to search the forum, start here:

This is great to hear! I'll be ordering mine here soon. Might come in place of the dp's now. ... :/BiGMaC said:

Ok, so there was a bit of misinformation pertaining to the factory intake box here that I want to clarify:
#1 I took a look at my factory intake last night from my 2014 SHO and it DOES have three drain holes at the bottom of the box. Two are under the intake itself and 1 where the outside inlet meets the factory inlet box. See picture below:
#2 Outside inlet has two 90 degree bends. where any water would have to hit before it hits the filter element. By then, it would drain out the bottom. See picture below:
#3 Pertaining to the water concern, I'm assuming Ford put holes in the intake box for a reason. If you take a look at my intake box, it shows clear signs of water & other outside elements from that inlet.
#4 Where I stand corrected, there is no DIRECT path for water to get into the intake. The hood seal closes off the front inlet, however, water can still get through the bottom radiator portion at highway speeds. The front radiator has a rounded piece that blocks direct water from making it into the inlet. See below:
I am still not 100% convinced that the MDesign still doesn't need a fail safe for water. I love the look, but I don't believe that water never makes it into the sealed canister; I think that is a bold statement given the drain holes in the factory box... My factory box shows that water makes it into the intake box...
Thoughts?

Interesting....
The odd thing is the placement of the drain holes. Why is the bottom of the tray "squared off" ? The section is almost squared off. Why wouldnt it be smooth on the bottom to allow for the water to run to the drain holes? It definitely held some bit of water at some point....almost look like salt form the roads.
From the others who have this setup, and have had it for a while now, I dont think there is any issue but I can see where you're coming from.

I've personally tested the MDesign CAI on my personal vehicle for over 40,000 miles through Michigan floods, heavy rain and snow with water never entering the intake and many other users have done the same. In the off chance that droplets of water enters the intake that still would not cause any issues.
The concern with water entering an intake system is the effect of hydrolock which is going to be a slim chance. Those three tiny holes would not stop an engine from hydrolocking as you would need a good amount of water in the intake to hydrolock in the first place, which if that were the case the water would be sucked up by the intake before being able to drain out of those holes. If you really wanted to attempt to get water in the intake you would need to: (1) completely submerge your vehicle up to the hood or (2) feed a hose directly through the grill, up against the hood and into the air inlet scoop. I understand your concerns though as stated before with many intakes out there in the wild and members using 3100 PSI of water on the vehicle there has not been any issues. Also the aerodynamics of the car, the location and design of the inlet, and the streamline effect while in motion will also deter the possibility of a large amount of water entering the intake inlet.

I guess short of disconnecting and inspecting the intake after a heavy rain storm, you will never know if water made it into the intake canister. Saying no water is mostly unbelievable. I'd also be interested to scope the intake manifold, inner cooler, and cylinder to see if there is any signs of corrosion due to water intake. Hydrostatic lock isn't the only bad thing that can happen to an engine if water enters the cylinder...
With all that being stated, I'm sure MDesign is an excellent functioning intake system. I think it looks great, looks well built, and would perform really well on the track.
I am an engineer by trade, and I like to look at things from all angles given my investment in my vehicles. My apologies for the questions / comments on this stuff.

I'm running an MDesign CAI on my SHO, and ya all bring up good points. I think an easy fix would be putting a small 1/16" drain hole at each end of the canister on the bottom. It'd be out of site, and if water did so happen to get in there it could drain out.
I will say today was one heck of downpour going to work this morning in the Chicago area. I tend to drive cautiously in heavy water with all the pooling on the side streets, but I made it to work, so nothing horrible happened. If I ever run into another downpour like this on the way home and if I have time I'll try taking it apart to see if any water got into the system.
So far I've been very happy with the CAI though.

It would seem that if enough water entered the intake to cause a problem it would be turbo damage. As an aside I pressure wash at 3100 psi weekly at my house. The upper front clip is sprayed for a total of 5-10 min at 2.5 gal/min. No water problems... I dismantled the first time to be sure. I appreciate that the engine is not running... But it also can't generate 3100 psi equivalent suction.14SHOCAR said:
