Steeda Intake vs. "Stealth" Intake

Well, I just installed the Steeda intake for my 2.3 ST, and all I can say is ...

WOW!

Not only is the car louder on WOT, but I can actually "feel' the performance difference in the seat of my pants.

And I don't think it's the louder noise that's fooling me either. The car really appears to be accelerating faster than it was with the Stealth intake.

Don't get me wrong. The "Stealth" intake is good if you want a cost efficient way of getting rid of that 6 ft. monstrosity that Ford put in. Plus, the Stealth intake still retains the stock resonator box, which has a 90 degree bend in it.

There ain't no bends in my new intake! (also, whatever concerns there might have been with hydrolock are no gone with the installation of the Steeda). So when Steeda says that their intake makes 6 hp. to the wheels, I can believe them.

I will try to confirm that extra hp the next time that I go the the 1/4 mile track (Saturday looks good, but it's supposed to be 85 degrees out! Not quite the cool and mild 55-65 degrees that it was the last time I went).

Still, I might be going anyway ... just to see.

Doesn't the Stealth CAI also give +6whp? That was on a D20--but I doubt that matters that much.

That is unknown.

BlazingCopper_ZX3 (the "inventor" of the Stealth intake for '05 up Foci) had never done a baseline test of his vehicle before he put on his Stealth intake.

The Stealth CAI hits the DynoJet!

And we can't compare his dyno results with stock hp numbers that were received with other D20's, as he dynoed his car at a high altitude testing facility.

Now, I'm sure that the Stealth is better than the stock 6 ft. long set up that Ford put on the car.

But as I said before, the Stealth intake still retains the stock resonator box. And the box causes the air to take a 90 degree bend as it exits the intake manifold before going straight down to the MAF tube/filter.

That can't help!

So would removing the resonator help with the power or no? I've read that the resonator left on with the stealth enhances the sound tone.

It definitely would. Think of the resonator box as a "sound muffler". And as we know, most "mufflers" reduce noise, at the expense of power.

Problem is, with the Stealth set up, the resonator box is an integral part of the Stealth system's intake. Because it is the stock resonator box that hooks up to the stock MAF tube.

So without the resonator box, you would then have to figureout a way to hook up the MAF tube to your intake manifold inlet.

With the Steeda intake, the stock resonator box is eliminated, and the stock MAF tube is replaced by Steeda's own MAF tube. Their intake then directly fits onto the stock rubber hose that comes off the intake manifold.

The stock intake resonator box on the 05/06 Duratecs has to turn the airflow 90 degrees downward from the intake manifold so that it can meet up with the top of the MAF tube that sits directly below it.

The Steeda unit is "straight", and therefore makes no such "turns".

Couldn't you use some flex-piping (like from the Ice Man intake thingy) to connect to the Stealth CAI intake piping? You know, to bypass the resonator?

I believe that a 3" flexable elbow may work rather nicely. I will pick one up tomorrow and give it a try. I'll let you know how it works out.

Sweet. The Stealth CAI is the next mod I'm planning, if the flex piping can be used instead of the resonator to get more power I'll be happy.
