Why new intake/manifold design for 2025 Maverick?

[fstlan3]

I don't believe I rebutted your answer. I shared my reasoning and expressed confusion regarding yours.



From what I know, a single LSPI event has the potential to destroy an engine. If Ford has linked intake valve fouling to LSPI then it would certainly seem that valve fouling has the potential to scrap an engine. This illustrates the source of my confusion: You say that Ford added port injection primarily to mitigate intake valve fouling. You also said valve fouling is not a major concern. These two claims seem at odds to me.


This has been my assumption from the start. You often read on forums such as this one how this or that manufacturer scrimps on costs, and designs their products with planned obsolescence; they are meant to hold together only long enough to get through the warranty period. Adding port injection is not an inexpensive redesign, and if you are correct doing so would seem to belie claims that Ford doesn't care about the long-term durability of its products.

Whatever the reason, it's a welcome design change, whether you believe Ford is fixing an old problem or improving an already good design. Thanks for the civil discussion.

I’m probably coming off back and forth but just doing my best to generalize with a summary of about 10 years of development experience through the years. Yes LSPI is very bad. Has it been a root cause destroyer of inline EcoBoosts? Not that I’m aware of. However with the increased chase for efficiencies and the learning experiences from the first generation nano in a truck application, it’s been a silent goal. Catastrophic LSPI isn’t on the radar. Yes it can happen but I wouldn’t call it consistent by any means. The factors leading to it however have been and it’s why manufactures besides just Ford have gone away from strictly direct injection. The limits of what is defined as LSPI in testing for us is more or less heavy knock. I don’t want to mislead anything with statements about these things so I’ll repeat these are not made in any official capacity and I’m not meaning to infer or cast doubts on engine qualities. I don’t want to keep cracking open deeper into this as I worry a poor image could be formed about this and that’s not my goal here. Also there is far more to everything in the design and engineering than I am made aware of so just because it’s what I was told doesn’t mean I have a basis of understanding of what else was going on to make that decision. I’m inferring the outcome from years of processes and data, though it was stated directly that carbon buildup was a consequence of the original direct injection design. I know the EGR redesign was another focus towards efficiency and longevity. Yes there is tons of nickel and diming that goes on but I do feel Ford does do a lot towards customer focused design. I can’t speak at all on how design is affected by warranty but I’m assuming that a lot of these processes were inspired by it. I hope anything I’ve said has at least made some sense. I’m also not trying I’ve represent myself, I just know enough to clearly make me dangerous lol.

What was the reason you wanted to install the S&B Intake?

same reason as any intake, looks neat & makes whoosh sounds.

the air path on the new is vastly improved. someone will probably make an intake for it anyway, because it's all about the whoosh.

Or the possible hp gain

quite intuitive. if you design an engine to be certain it lasts >200k miles it's going to cost more than one that needs to last 60k.

statistically it's the lack of proper maintenance that kills modern engines. things don't just fail, very often.

Or the possible hp gain

no way on a stock engine. the stock airbox could be a performance issue once sufficiently modified, but Ford is not going to leave free horsepower on the table in this day and age. most intakes are hot air, at least S&B is enclosed, but one look at that new short intake right behind the grille tells me all I need to know.

I agree 100%! Preach it, bro!

I had addressed Cody the OP.
I was hoping he would answer. I didn't know if he had Dyno data showing more horsepower from a S&B intake.
In a Maverick, if you want more engine sound just turn the volume up

Fuel line Q.D. into upper fuel rail (above intake)

Upper fuel rail fuel line and q.d.

Directly below previous image.
Noting the metal fuel line running down the side of the engine to the lower fuel rail.

Side of engine, driver side.
Tracing the route of the metal fuel line along the engine, and up the back side to connect to the upper fuel pump.

Same side of engine, with upper fuel pump location in view.
T-junction for fuel lines, left routes to the upper fuel rail.
Up to the upper fuel pump.
Right goes out to a fuel line connection near firewall, presumably to the tank?

Upper fuel pump on top of engine.

Now under the airbox and, under the intake.
Lower fuel rail.

Lower fuel rail, another angle, better shot of the fuel rail plug and connector.

Passenger side now, upper fuel rail 'end tank'. (With a QR code on it?)

I’m curious - what does the new short intake tell you? Thanks!

At $350.
Was there any particular reason you wanted to install the S&B Intake?

No particular reason. Just heard from previous owners that it was one of the better ones in the market. Sorry it took so long to answer, I wasn’t receiving my notifications from the post.

Have you found anything or you going to just stay with OEM Style for a while?

Have you found anything or you going to just stay with OEM Style for a while?

Have not found any intake yet. S&B does have one in the engineering phase that I have seen. Nothing else out there that I can find.

I do have a 3 inch custom downpipe with kooks cat and custom exhaust. I also have the CVF FMIC.

it's taking air from the top of the grille which is as cold as it's going to get - much better than a K&N open in the engine bay - and it's a very direct path from the inlet to a small airbox, and into the intake manifold.

I highly, highly doubt an aftermarket intake would improve upon this especially on otherwise stock trucks. I'd vote that removing this will decrease performance for most if not all trucks.

Thanks for the info, really appreciate it.

That is what I was hoping to hear. I have installed various CAI units on multiple vehicles with limited satisfaction - I’m really going to try to resist temptation on my Maverick.

My Borla Type 3 catback arrived at my Ford Dealer yesterday however. Will pick that up today & load a new blade in the reciprocating saw yay.

(I meant to post this last night, but didn't hit Send)
Well, I think it at least is ingesting air from somewhere in front of the vehicle by looking at the intake path.

But, I can't confirm where, by looking from the front grille. No obvious intake tube extending in front of the radiator.
The air can't be all bad even if just pulling from just above the radiator without an exposed intake tube. Assuming your moving, with even minimal air flow it should provide fairly decent fresh air intake.
(I'm sure someone has pulled the front clip off to install an intercooler to know first hand.)
