I stuck the ST 'air velocity stack' into the place where the 'snorkle delete' part came off.. tonight.
NOW.. Whoo Hoo my car is able to leap tall buildings in a single bound... is faster than a speeding bullet.. and more powerful than a locomotive...

Actually all I did was drive around a little after sticking the part: CV6Z-9A624-B ($5 bit of plastic) on my car.
Basically having the ST part on my SE makes my car SUPERCAR !!!
And worthy of mention in the all time car hall of fame.

The ST bit seems to make the intake slightly quieter than just leaving the intake hole in the front frame with nothing on it.(after the snorkle delete)

I can say the car performance is 'better' with a K&N and the snorkle delete. And also with the ST part on it I am full of confidence all Porsches and Corvettes and GTr types better watch out. [nutkick] (no such claim for big V8 Mustangs... I know where my loyalties lie...)

And since I believe I am the first to stick a (2013) ST air velocity stack on my MK3 ride...I accept the thanks of thousands of Focus mavens for bringing this wonder to us all. [angel]

See the thread in MK3 engine mods: http://www.focusfanatics.com/forum/showthread.php?t=297795

Basically you buy an free flowing aftermarket air filter. Either Green, or K&N, stick that in. Open up the front top plastic under the hood and remove the giant crazy gizmo called a 'snorkle'. Which channels the air to the air intake opening into the front frame member. the snorkle's only purpose is to quiet the air entering the engine. And it restricts airflow. Ripping it off is a good way to gain the advantage of the free flowing air filter. The snorkle delete takes all of ten minutes if you know how to take off the push tabs.. [rofl]

Someone mentioned the ST part, and I decided that would be great to stick on.
So I did.[woot]

If you do not 'believe' and clap your hands.... Tinkerbell will DIE!!!

Actually in general the K&N or 'Green" filter is Ok but with the 'snorkle delete' it does give a bit of added horsepower.. Enough many say they can feel it in thier 'butt dyno' (me included)
Better low speed takeoff.. engine just feels better (at least to me) and accelerating is better. it feels more like a car with a real engine instead of two squirrels running in a cage under the hood.

Now this is with a manual tranny.. so i can be anywhere in the powerband when I want.. (unlike the DCT)


So the aftermarket filter and snorkle does give some added juice. The little ST part is just icing on the cake.. And probably does not add anything besides bling.

After I found a little bird dead inside that front end part of the car.... Taking off the horizontal snorkel sounds risky to me...
Pictures: http://www.focusfanatics.com/forum/showthread.php?t=421794

Those are good pictures of the parts.
The big stock snorkle is a real monster.... Ugly too.

The little picture has the ST part that goes in place of the big snorkle.

Taking pictures inside the front would be really tough unless as the picture taker did) remove the whole top plastic etc.. Whch I am not gonna do just to give somebody a picture.

The ST part is different than the base of the stock snorkle anyway.
I did cut up the stock snorkle base before I read about the ST part fitting in. The base of the stock snorkle does not have the velocity stack like extrusion the ST part has..
And that bell like bit, small as it is, is what you want there, if you are gonna bother at all with anything covering the frame opening.
After I found a dead little bird inside that part! I'm worry if anything will be covering the frame opening... I'm not sure about the risk of the snorkel delete now....

Soooo I really wonder if that velocity stack really makes a difference. In essence, all you're adding is a little curve/bend for the incoming air. I understand fluid dynamics but it shouldn't make that much of a difference as opposed to just removing the snorkel. Then again, the engineers at Ford decided that they had to have something on that inlet instead of not.

I did a 'ram' air design by using a old license plate to divert air directly from the top opening to the inlet and that helped. We really need an ebay version of the tube that Ford is trying to sell for $$$.

The Ford Racing cold air intake ram is pictured below. AFAIK, it is only available in the complete kit that includes a K&N air filter.

I have read it is a b*tch to install.

Best price I have seen is $175:

Now I'm curious because I did a snorkel delete and added a steeda cai wonder if that ram air part would help?

The Steeda CAI would cancel out the benefit from using the ducting to the grille from the stock air box feeds for only using one feed, as well as being open under the hood to the driver's side fender creating a loss of pressure drop across the front of the car.
