What's up, guys?
Adam here with americantrucks.com.
Today we're taking a closer look at, installing, and Dynoing the Roush Performance Power Pac
Level 1 available for the '15 to '17 3.5-liter EcoBoost F-150.
You should be taking a look at this Power Pac if you're looking for pretty straightforward,
simple bolt-on mods that make pretty impressive power gains right out of the box.
Now, the Roush kit here does come with a Roush voucher code so you can flash it right at
home on your laptop if you have a J2534 interface tool or a device to plug in your OBDII.
You can pick that up at your local auto parts store or take it right to the dealer and have
them take care of it.
So we strapped down our 2017 3.5-liter EcoBoost F-150 to the Dyno to establish a baseline
or stock run on 87 octane in the tank.
We came up with 298 horsepower and 351 foot-pounds of torque at the rear wheels.
So, then we obviously installed our Roush cold air intake and tuned it to the Roush
voucher with the Roush diagnostic tool, strapped it back down to the Dyno on the same octane
level to see what we would make and we came up with 352 horsepower and 386 foot-pounds
of torque at the rear wheels.
Now, our curve gains here are 114 horsepower and 103 foot-pounds of torque.
If you're looking for that simple bolt-on, this is a really good way to go for some horsepower
and torque.
Now, this one comes in at around 750 bucks and if you wanted to take it a step farther
to see even bigger gains, maybe even get some sound out of your EcoBoost which, let's be
honest, we all know we could use, you can upgrade to the Roush Power Pac Level 2 and
get the Roush cat-back included with those two mods I just mentioned.
Now, this one is gonna come with a washable and reusable dry filter, so no need to re-oil
it.
But also no need to pick up a new filter every couple of thousand miles during routine maintenance.
That filter has cotton gauze, double-layer wire mesh internally and externally so it's
doing a really good job of filtering out the particles you don't want and pulling in all
the cold air that you do want.
It also seals pretty good with the inside of your hood, keeping that engine heat out
and the cold air in.
It's also got polyethylene lightweight tubing.
It's gonna transfer over your factory sensor to the new tubing.
Has harness extensions.
I'll walk you through all of that process in just a second.
That install, by the way, is gonna get one out of three wrenches on our difficulty meter.
You can expect to get it done in I'd say about an hour, hour and a half including the time
it takes to actually flash that vehicle.
Now, like I mentioned in the beginning, you do want to have that J2534 interface tool
or diagnostic tool.
You can pick that up separately as it is not included in the kit.
Once you do have one, all you need is your PCM code and a laptop to get the job done.
First couple of steps on our uninstall, we'll use our flathead screwdriver, an 8-millimeter
socket and ratchet would do the trick as well and we're gonna loosen up the three clamps
holding on the tubing from our factory intake.
Two of them are right up top here.
The third one is a little bit farther down toward the turbo.
And the head of that clamp is going to be on the inside so it'll be a little bit harder
to reach, but it's still possible and still doable.
So, I got my flathead here.
I'm gonna loosen those clamps up and then we'll remove the sensor.
All right, with the three clamps loosened up here, you can just pop off that temperature
sensor.
That'll snap right off with just a simple pinch.
At this point, we can remove this portion of the tubing.
At this point, I'm gonna use my panel removal tool.
A flathead screwdriver could do the trick as well and we're gonna remove these two plunger
style push pushpin clips holding on our inlet to our factory radiator shroud.
We're gonna slide the prong over top, pull that one up.
That's one portion.
Do the same thing for the bottom and it comes off in one piece.
The plunger first, then the bottom.
Now, this is loose and good to go.
All right.
Now, we got our 13-millimeter socket and our ratchet, we're gonna remove this bolt holding
on our factory air box to the side of our engine bay.
I'll just break this loose and remove it all in one piece.
All right.
Before we can remove these, there's a couple of yellow clips holding on a wiring harness.
You can pull straight up on those and they will come out.
With that wiring harness removed, you can just lift straight up on the air inlet and
your other hand on the other side of the air box, pop that right out of position and set
it aside.
So, we finally got our factory intake off for 3.5 EcoBoost F-150 and on the table here
next to our Roush Power Pac Level 1 cold air intake.
Now, as you can see, there is just pretty much differences in every aspect of the cold
air intake compared to the stock air box.
The biggest difference being the comparison between our new cotton gauze filter and our
factory paper element filter.
Now, this thing does an okay job from the factory, but if you're looking to really streamline
your airflow coming into your intake, this is the way to go.
This is a reusable and washable cold air intake filter that's made with cotton gauze layers
with a double-layer mesh filter on the inside and the outside to make sure it's filtering
out all that nasty stuff you don't want getting into your engine.
The rest of it is going to be made from a really lightweight polyethylene material.
This has a textured black finish on it, looks a little nice under the hood, gives it a stealthy
finish, and it blends in really well with everything else you got going on.
Now, your heat shield here will come with an EPDM foam seal built in to make sure it's
completely enclosing your filter, keeping out that engine heat and keeping your cold
air in.
That's gonna really help to streamline that cold air process.
Getting this installed is pretty straightforward.
I'm gonna show you how to do that, then we're gonna flash your truck and see what kind of
power it makes.
We do have to transfer over the factory temp sensor from the stock tubing over to our new
Roush tubing.
All you have to do here is twist it out of place.
All right.
You're gonna take that and put it into our new tubing here.
Just line up those shades from the inside, press it into place, twist it to lock it.
Now, since this is being relocated, we're gonna use our sensor harness extension here.
That'll plug into the factory end in the vehicle and this will extend all the way over to the
temp sensor.
All right.
Next up we're gonna have to transfer over our factory inlet duct.
We're gonna take our 8-millimeter socket.
I'm using a cordless impact, a ratchet can also do the trick.
We're gonna remove this bolt here, transfer over the duct to our new one and reuse that
factory bolt.
First step of the install here, we're gonna drop our air box and factory air inlet duct
assembly back into the truck.
There are snap down points that will actually hold this into place here, then we're gonna
replace our push pin clips on top of our radiator shroud.
So, the next step here is to take our filter assembly with the tubing.
We've got our appropriate clamp tightened down a little bit here.
We're gonna slide that through the inside of the air box.
We're gonna rotate it so that the pre-drilled holes on the tubing here line up with the
threaded holes on the factory heat shield.
Once we have this bolted down, we'll make sure our sensor gets put in position.
We've got our hardware provided by Roush.
I'm gonna thread that through by hand and then use our 10-millimeter socket and extension
to tighten them down.
All right.
We're gonna take our factory temp sensor and put that into the pre-drilled hole on the
new tubing.
Once we have it in place there, we can just twist it to lock it.
Now, we have a temperature harness extension that'll go onto this side and actually extend
that factory harness over to the new position on our cold air intake.
All righ, at this point, we can install our new textured black tubing from the Roush intake
kit.
You wanna make sure you're assembling the couplers into their appropriate locations.
The rippled one goes right next to the air filter.
Then you'll have, again, a larger one for the larger intake tubing and a smaller one
for the smaller tubing.
Now, you wanna make sure you are assembling them before you install them into the vehicle
with these clamps, just tighten them down nice and snug to make sure they're not moving
around.
That's what we have done here.
We're gonna be able to pop them onto the tubing, then tighten down all six of these clamps.
Now, we can go back and tighten all these down.
We can take our sensor harness extension and plug that into the factory harness.
Now, this one, we can feed underneath so that it's not getting tangled up at the top and
plug that into our temperature sensor.
All right.
Last step of the install here is gonna be this weatherstripping and it conveniently
has these push pin clips that'll go right around the edge of our heat shield here.
I'm gonna start back here and they will literally just snap into place.
You can just feed this along the edges.
It's pretty self-explanatory.
So, with that excess, you could just cut it off.
I'm gonna leave it here just because once the hood shuts, it'll actually just seal against
the top of the hood.
So, it's not gonna be a problem there.
Now that that was the last step of the install here, we can actually get to flashing our
truck with our Roush voucher.
At this point, we're actually gonna use our Roush voucher to actually flash our PCM using
the Roush diagnostic tool on our laptop.
Now, you are gonna need your own J2534 module device to plug in to your OBDII port.
We have our own here, you can pick one up your auto parts store or you can order one
online.
There's a number of different ways to go that route.
We've got ours plugged in already.
It's reading our VIN.
We're in the Roush diagnostic tool program.
All we have to do now is go into the module programming tab.
We're gonna input our PCM code or our tear tag code.
You can find yours either using an x4 device if you have your own handheld tuner or you
can go under the hood and actually pull the PCM out of the vehicle and read it on the
top of the sticker.
That's what we did.
We've got our code ready to input.
So, I'm gonna put that information in, I'm gonna input our voucher code and our voucher
family code, and we'll be able to actually flash this thing.
We're gonna go into module programming.
We've got our voucher code and our voucher family code input.
We're gonna redeem that.
So, redemption successful, flash is enabled.
We're gonna hit okay to move forward.
All right.
From here, we're gonna hit flash with our flash button down here.
That should take us into moving forward.
Yes.
All right.
Make sure your ignition is on at this point.
All right.
At this point, the flash is complete and we're good to go.
That's gonna wrap up my review, install, and Dyno run of the Roush performance Power Pac
Level 1 for the '15 to '17 3.5-liter EcoBoost F-150.
If you're looking for a simple cold air intake bolt-on that does a really good job of streamlining
your airflow into your intake manifold and turbo, this is a really good way to go and
it comes with a tune from Roush to make sure you're picking up some pretty serious gains.
As you saw before, we're looking at 50-plus horsepower, 30-plus pounds of torque, and
over 114 horsepower under the curve and 103 foot-pounds of torque at the rear wheels under
that curve.
Pretty impressive gains with a very simple kit here.
