Was looking at the Roush website and found their new CAI for the 2011 5.0. Nicest looking CAI I have seen so far.

here it is

Looks very factory so on that note great job! On the other hand, it doesn't look like it's effectively any more than a K&N filter on the stock unit.

 

I had it for my 2010 GT, didnt like it, i returned it, was too flimsy and the front didnt connect directly to the front air duct., left a wide open space and just didnt look right.

Went with the K&N filter for now.

 

You wonder how any of these CAI's work better than stock with the hood down? I can not see them out preforming the OE intake with the hood down because the air duct pulls air from the front on the OE. Even if they gain a few hp is it worth the 300+? They should test it stock with the hood down and then add the CAI and test it with the hood down.

 

Well, just by fluid dynamics, it would seem that Steeda's big elbow style would have an advantage in some ways. So I would say that would win out in this comparison.

I am not sure how they test them to get the numbers they do so I can't comment there.

Edit: I think most companies know it's not a perfect scenario but if they can create any better a flow over the stock then they have done their jobs I suppose.

 

I agree. Not worth the money you pay. I do like the way the Roush set up looks though. Ford said that they only lose about 8% in their new design. They have the K&N in the ford racing catalog and should have the same performance for less money.

 

Correct. I ran the Roush for a day, didnt like it, got the Ford Racing K&N and felt the exact same, for only $54 instead of the $300 for the Roush. Roush support was nothing special either when I called. American Muscle was over the top great with tech support.

I am trying to keep the car as original as I can (the way I purchased it), so in 15-30 years, can be unique lol. Sounds weird, but so many go crazy and nothing is original. I need another one to play around with !

 

Steeda intake pulls air like the OE. It's underneath and hooks to the front air intake like the OE. You just can't see it in the pics.

 

i don't like the look of the elbow on the roush, especially with that frilly straw type thing up front.

 

For the 2010 I heard it was garbage.

 

This is what Granatelli said about it.

"WE dyno'd this intake prior to the construction of our new twin turbo kit for the 5.0 4v - it made a repeatable 5hp and 3ft/lbs. 8 and 8 never happened - sounded better as well. Ford did a great job this time with the stock stuff."
