This. I'm not denying that it won't give you a little HP, but 9-12HP isn't worth $300+ to me. The only reason I have one, is because I was able to get it used for only $100. I can live with that price.

From Paul Randle, Ford's chief engineer on Bullitt:
“Colder air reduces intake losses,” said Randle. “The new cold-air intake has shown a reduction in rise over ambient temperature from 50 degrees down to 17 degrees Fahrenheit. That equates to more horsepower and more torque in all driving conditions.”
Another engineer that used to post here made the point:
Without the new hood liner, you will not get the full seal and that will make a significant difference in real street performance, as well as the peak power.
The good news for anyone buying a 2008.5 or later Mustang(V6 or GT) is that they will have the Bullitt hoodliner on their car.
From a forum member:
The 08 Bullitt intake, everything you wanted to know and more, Dynotesting...
Hey guys,
Here's my Holiday present to everyone. Our friend Kevinat Clevenger Ford parts here sold me a 08 Bullitt Mustang intake. From there I installed it on two different cars, an 05 and 06 ManualGt, as well as taking it to C&L Performance to have it flow tested and to compare it to the stock airbox as well as their air intakes too.
Firstthe fitment and installation. Very nice, but I wish I had an 07 to try it on as Ford redesigned thecoolant hose routing on the 07 and newer Mustang GT's and I thinkthat was the issue here. Not that it won't fit an 05-06, it will, butits just a tight fit with the two resinator boxes on the bottom ofthe Bullit air intake tube. I LOVE the airbox, it fits over the frontof the cars headlights and seals to the hood completely isolating theairfilter from under hood air temps. The air filter is a non-oiledtype as it reseambles that from an airaid system but it has a 4"opening and is around 9" long. The airtube itself if the factoryplastic with two huge resinators below it which are there just tohelp quite the air flow. The MAF section is right around 81-83mm indiameter, just abit larger then the GT airbox. I've included photo'sbelow so you can review it as well.
Tuning, needed or not? YES! Imade the dyno runs like this, on the first car I installed the stockair box and ran it three times and then installed the Bullitt airboxand did the same. With both intakes I had the stock tune installed inthe car. Sure enough wtih the stock airbox and tune it went rich downto the high 11's and low 12's like normal. When I installed theBullitt airbox it went lean, very very lean, in the mid to high 14's.Yes, this intake requires a tune. Any tuner can verify this as wellby looking at the stock Bullitt tune, which SCT has in theirdatabase, and noting that the MAF adjustments are different for thenew Bullitt air box.
Power, how much did It gain? SinceI had to tune for the Bullitt intake I did so with the 91/93 octanetune file so I could compare it with a C&L Racer intake tune.
First I stared with the car completely stock with the stockairbox and stock tune and made a surprising 269 rwhp and 285 rwtq,this is actually a little high but for a stock tune it is what it is.Most make 260-265rwhp and 280-285 rwtq.
Next I installed the Bullitt intake and my high octane tune adjustments and set the a/f around 12.7-12.9 and it made 280 rwhp and 305 rwtq at best, it made a few lower Hp numbers but these are the best.
Finally I reinstalled the C&L Racer intake and used the EXACT same tune as far as spark timing and commanded a/f goes and we made 288 rwhp and 308 rwtq.
So as far as dynotesting goes it shows that there is a definite gain over stock using the Bullitt intake but it does REQUIRE a tune because the a/f is very lean without one. Also the gains from the intake aren't as much as a normal C&L intake with tune.
The max number gains are only 11rwhp and 20 rwtq - but the gains in the midrange are well over 15 rwhp and nearly 30 rwtq at different points on the graph using the Bullitt intake over the stock one.
The gains of the C&L Racer over the Bullitt ar eright around 8 rwhp and 3 rwtq and the Hp gains are mostly above 4000rpm's and there is a gain of around 7 rwtq over 5000rpms using the C&L Racer too.
Flownumbers LeeBender of C&L Performance was nice enough to flow test the Bullitt intake to compare it with the stock intake flow numbers and of course the C&L Products too. The stock airbox maxed out at just over 551 CFM. The Bullitt was huge improvement over stock at 823cfm. The C&L 83mm Street intake with the " No tune Option" insert flows 885 and without the insert 997 cfm. Then the Racer withits 95mm housing flows more then a 1000 CFM.
I was there and helping with the flow testing and all numbers are unbiased and I stand behind them.
So in conclusion, the Bullitt intake will be a nice addition to any 05 and newer Mustang GT. The airbox is the coolest on the market, the air filter is the un-oiled type for those of you worried about that, truly it means very little but either way. The fitment is a little tight but it does go. Horsepower numbers are right there with alot of other kits on the market like K&N, Airaid, and AEM. I'm sure I may be able to squeeze a bit more out of it too with some more mods on a car.
These tests were performed using the Diablosport Predator and my custom tunes.
Thanks, and happy new year to all!

CAI's must do something to increase performance, although not all are equal. Like someone else said, I got my FRPP CAI because it looked good and it cost me $150. With the stock tune I kept getting codes telling me that I was running too lean. I guess that means that the CAI is doing what they said it would, increase air flow. In turn I used my Diablo inTune to load a tune that increased the fuel amount which increased my horsepower.
That said Ford probably did spend millions on R&D but they have always tried to sell Mustangs at a lower price point so they would never include a CAI in a base or GT model even if it only cost a few hundred because they don't want to increase the cost to the consumer and possibly lower sales.
Cdynaco, great post, thanks.

My point is Ford optimized these engines to run with the stock airbox and they did a good job. Just because something causes you to run lean doesn't mean it will give you power. I can pop my hood right now and pull a vacuum line or two and run lean. Does that mean I will make more power? No it just means I am no longer in that optimized range the tune runs best in. You got your CAI for cheap thats cool and kudos to you however would you drop $250-$300 for the 2-5 HP performance increase? I know I wouldn't. I would rather keep it all stock and get a tune from a good tuner and see even better gains for around the same price. The cost of these cars from the factory is is such that another couple hundred dollars isn't going to scare anybody away.
