Intake mods FOR SOUND!?

Most of these diesels have a stock intake box thats good for around $500 horsepower, and I am under the impression the 6.0 does as well.

I like to stick with the OEM air box and filter because I feel like its the best for protection and filtering. One thing I dislike about OEM airboxes is the muffling of the turbo and intake sound.

Im new to the 6.0 stuff so what are you guys doing to improve/modify the OEM stuff? Different tubes? Holes?

We were at the boat launch the other day and there was a guy there with an excursion and his turbo was whistling like crazy when he was pulling off the launch. Would like to emulate that sound.

The only real mod for the stock intake is the ZooDad mod. Have you looked that up?

Well a couple of things...

That whistle has nothing to to with the intake or compressor wheel in the turbo. It comes from a 10 bladed turbine found in the pmax, 03 turbos, and some of the other larger turbos built. An intake will not increase that whistling sound. But it can increase the whooshing sucking sound when getting on the turbo.


Also it is 100% false that the stock intake limits you to 500hp... I am still unsure of where this rumor started. An intake will add about 15hp max... So i guess if you were at 485hp and add an intake for 15hp then that is the limit. Although there are many people including myself that have easily broken the 500hp barrier with a stock intake. I made over 530hp with just turbo and injectors on stock intake.


2 best advantages of an aftermarket filter is it can add up to 15 hp and makes changing the filter much eaiser. The stock air filter is a real pain to change

No I wouldnt say it "limits" to 500 that is a misunderstood. I was implying that it starts to become a more noticeable restriction at the higher HP levels (500).

Meaning that maybe stock the aftermarket intake might free up an extra HP or two, but once u start talking 500, then noticeable gains can be found from an intake.

In your opinion, is an intake a worth while investment to a truck with maybe a milder state of tune (375whp-400)? Or is the OEM just fine for that. If its going to free up 10-15 HP at even that state of tune, I would consider it a worth investment.

That post above this one was for you, and also since you brought that up, ive came across stuff about the '03 turbo being louder, whats the difference? Blades? Does it make power differently? and I guess is it more or less prone to sticking?

First I would make sure you have your truck built for reliability... head studs, egr, delete, sct tuner, exahust, monitor, possibly a fuel system, etc... all the bulletproof stuff.



But when it comes to hp mods your best bang for your buck after tuner will turbo and injectors. but that is just most hp for your money...


Intercooler, ported intake manifold, bigger turbo, water/meth will lower egts and get more air flow and lower your egts. These are safer/cooler hp mods


Ficm tuner, larger injectors, larger nozzles, high hp tunes will get you more fuel, and potential raise egts and cylinder pressures.


The best thing is to get a good combo going.

Meaning that maybe stock the aftermarket intake might free up an extra HP or two, but once u start talking 500, then noticeable gains can be found from an intake. I personally feel that the gains from an intake is a constant, not an exponential equation. But i could be wrong. I think it will be a pretty consistent 5hp-20hp. Even on a 1000hp truck I don't think you will gain 150hp from an aftermarket intake.

In your opinion, is an intake a worth while investment to a truck with maybe a milder state of tune (375whp-400)? Or is the OEM just fine for that. If its going to free up 10-15 HP at even that state of tune, I would consider it a worth investment. I plan on running my stock intake above 600hp... or until i get tired of changing out the stupid stock one.

Read answers above in read... now these are just my opinions

I have a 6.0 specialist that is located near me. I was planning to leave the bulletproofing to him because hes just done it so much. I am picking the truck up Tuesday. I am taking to him and having him look it over. Right away I am having the coolant flushed, the oil cooler replaced with OEM, and egr cooler delete installed. I am looking on ebay right now for used SCT x3's and I have another friend who owns a performance shop getting me quotes on a turbo back exhaust and an edge evolution CTS to monitor. I'll also order a blue spring once i get the truck I just want to make sure its not in there.

The guy I'm buying it from has had the truck serviced by a ford dealership since day one, anything they recommended and has all the service records. Would the ford dealership have told him to do the spring? (kinda doubt it?). I just would hate to order it without knowing.

So thats what I have so far. The truck is a 6-speed manual with the stock clutch and 70k miles. No history of any issues with motor or trans.

The reason I was asking about the air box is because I am curious if its beneficial with the mild tunes I have planned. I am aware of the FCIM tunes and turbos, and that with even with stock injectors, I can see gains from an aftermarket turbo, BUT two things:

No head studs (yet) and I hear the stock clutch cant even handle an aggressive street tune, so forget about FCIM and turbos and injectors. If i get the truck and I deem its going to a worth while investment, I would likely do studs, turbo, and clutch at the same time.

It kinds sucks that the clutch is a limiting factor but if I drop a grand on a new clutch then I might as well count on doing the studs too cuz headgaskets probably go soon after I get the power up?

Also the intent is to get a used SCT and have eric or vivian do a tune that gives me the max they think the stock clutch can handle for the time being.
