All the info I'm finding out there is for the 15-17 trucks and nothing for the 11-14. Now everything is swimming with 2018 knowledge and I can't find much out there for the older trucks.

So with that said, is swapping an intake worth it on a first gen 5.0? I know there will be gains obviously, but would I see the type of gains the 15+ guys get? I don't see myself swapping cams, that's just too big of a job, but I'd love to upgrade my intake and have more top end.

I'd love more low end too, but that's a different story and I don't know where that's going to come from.

I was actually looking at that. Just didn't know how it carried over to the older engine. The only difference, as I understand it, is the intake cams. Which is a big difference and something I don't feel like digging into because 4v motors are a pain.

But I like the more linear torque curve on the mustang intake, the boss looks awesome, but I don't want to pay for it and then of course, the 2018 may be an option at some point but it isn't plug and play.

Right now with my tune, I get a huge surge as soon as I step on the gas that's not manageable and half the time I spin the tires whether I'm trying to or not. I have 355s and stock sized tires. I think the mustang intake could in theory throttle that back a big and may provide the gains I need up top where my tuner lets me rev to 7k but my power falls off at 5kish.

I'm just concerned that my cams are not going to provide what I need to keep pushing it that high and it's still going to fall on it's face.

So that's the dilemma.

I swapped the boss intake on my 13. It's an easy job, looks cool, definitely let's you spin it a little higher in the rpm band. If you don't take the truck to the track I wouldn't bother. I think it would really shine if paired with a better set of intake cams. Your truck will definitely lose some low end grunt and feel slower on a day to day basis under normal driving conditions. Don't know your gear ratio but gearing the truck would be a much more worth while investment IMO.

I'm not going to the track. That's why I was looking at the more inexpensive option with the mustang GT intake.

Maybe I'm grasping at nothing here and trying to fix a problem that isn't there. Just trying to get the truck to stop falling on it's face after 5k. If it would pull all the way through, that would be nice.

If you don't have longtubes on it all a manifold will do is keep the power flat past 5300 or so up to about 6200. With longtubes you'll make power to 6500 easy.

Never heard that.

I figured a car intake and a tune to make it work right would have a noticeable change.

Were there any improvements in the mustang intakes between 2011-14 and 2015-2017?

negative. Tuned multiple s197's with boss swaps without longtubes and they just don't make power like the s550's do. And your truck has similar cam specs to an s197 which has the baby intake cam.

So there's nothing to be gained at all with a mustang intake swap? I know it won't do what the newer trucks do.

I'm due for getting some tuning done anyway and the intakes are $50 and take an hour to swap out.

So I have the 5.9 with long tubes and the boss mani. I also have dyno runs stock w/tune, then boss before headers and boss after headers. With the boss it definitely makes power at a higher peak than stock. With headers it makes power at the same peak as it did before with the boss Mani only. Stock tune only peaked at about 5250 rpm, boss manifold only peaked at about 6100rpm, boss with long tubes peaked at about 6100 rpm also.
