Sealed air intakes 2011-2014 Mustang GT.

Good morning all.

I haven't posted in awhile so I thought I would update. When I bought my car it had the Ford bolt on special package. Roush CAI / Roush Axleback. Probably put on by the dealer.

I since then have replaced the Roush CAI with a factory one I purchased locally.

The reason for this is two fold:

1) The Roush intake blocks the driver side heat extractor with foam. Trapping hot engine air in that area of the bay. I didnt like this it was a really dinky solution to keep moisture off an open element filter. https://www.roushperformance.com/mustang-cold-air-intake-kit-2010-2012.html

2) With the heat trapped in there on a -4 farenheit day I would routinely see 110-120 degree IAT while in traffic. I am now basically staying ambient with very slight temperature changes sitting in traffic.

Now looking at all the S550 intakes most manufacturers are going to a closed box design. (Steeda, Airaid, Roush, Injen, aFe, etc)

However for the S197 crowd its dominated by open element "hot air" intakes. I don't plan on making huge power I like driving it on the street and opening it up down the back roads and taking it to the drag strip ( I can only imagine how hot the temps would get idling in the pits)

Does anyone have any recommendations for a sealed box intake? The only ones I can see are as follows:

(Unique design, not sure how I feel about the sealing technique)

(I don't like this design for the opening to the engine bay.)

(Requires a tune as it has a sizable increase to the diameter of the piping.)

( seems to seal nicely when installed properly, makes good power from independent review from Motoiq showing gains of 5-10 hp and 6-12 lb/ft of torque across the entirety of the curve with stock calibration)

Then we get to the cheapest option, stock intake with panel filter like AEM/K&N/AFE

One more option is the Airaid tube that works with the stock filter box:

I think most of the gains from any of these is eliminating the stock tube's accordion section and 'muffler' resonator sections. I say pick the one you think looks best as they all probably have similar real world gains.

I know there has been independent dyno's done on those tubes for other models. but I have not seen any for our cars. But they do pick up power when removing the baffling and the accordion section.
