aFe Power Momentum GT Cold Air Intake System

LopezST · Oct 8, 2022

Hello everyone, I am considering having a CAI installed in my ST and wonder if anyone has experienced any engine issues after installation besides installing hiccups. What's been the biggest drawback, if any? Was there a noticeable increase in MPG or HP for those who have one installed? I have constantly read the increased engine noise is great, but the rest is just fluff. Thank you!

As far as I know, there will be no problems. It could be something Ford could void warranty for BUT THAT IS A BIG COULD. That could be the only drawback I can see. I would contact Ford just in case, it never hurts. I would get it if I had an ST bur it will not noticeable increase gas mileage or power.

I’ve been running one since they came out on the Wife’s ‘21. Other than the clip on the drivers side turbo, install was pretty straight forward.

It seems to work pretty well. Small amount of throttle response increase noticed, but that’s about it.

Unless you're looking to add a tune and supporting mods to achieve over 100 added HP, it won't make any discernible difference HP-wise. It also will not add any MPG. It will add a nice look under the hood!

All helpful. Thanks!

I put mine in after the E50 tune was installed.
I asked if it needed to be retuned and 5 star said no.
However, others with tunes from ZFG say it needs to be re-tuned to gain maximum results.

It’s a subtle difference. One cool thing I liked about putting one in is now I can hear the turbos better. Which could be good or bad depending on the individual. MPG wise for road trips or longer drives I’ve noticed an improvement of 2-3 (@about 73MPH with normal cruise control, manual mode) City driving pretty much the same(Atlasblue makes no guarantees, individual results may vary).

I sincerely mean no offense with this post and I don't mean to come across as a know-it-all (I don't know much at all) but I can't buy the 2-3 mpg improvement with a new cold air intake.

For heck's sake, if that can be accomplished for a few hundred dollars, Ford would find a way to do it for a fraction of the cost and introduce it across the line. Improving MPG across an entire model line would be an incredible feat for the company and its CAFE numbers. They would be all over that.

The engine only uses what it needs, it doesn't need all the air that the OE intake system is capable of delivering while cruising at highway speeds. We're not talking wide-open-throttle. There is something else going on with the numbers here.

Think about it like this, if the engine is putting more air through it because the new setup is capable of supplying it, it's mixing more fuel with that air. What do you think that would do to the MPG numbers? I'd suggest you put a few tanks through it hand calculating the numbers. The gauge on the dash can be a real liar at times.

Okay, I'll step down from my soapbox now.

AtlasBlue2022 · Oct 10, 2022

No worries. I was getting about 21-22mpg on the freeway/highway on longer trips now it’s been closer to 24-25mpg just my observation. Same stretch of freeway/highway visiting family. Only variable that maybe changed is temperature & maybe weight since no1 packs the exact same way every trip. Also based on the numbers the car’s throwing at me. Not hand calculated. lol that’s why I put the disclaimer in there that there are no guarantees.

I"m not picking on anyone- I have not met a person yet who spent money on a part and didn't think his butt dyno or in reality wishful thinking didn't make a difference in some way!

I'm completely with @GearHead_1 on this point because we see it constantly on this forum. Whether it's a tune, an exhaust, or a cold-air system, you are going to see posts about increased gas mileage. It's NOT possible. I understand that most of you aren't engineers and don't know a BSFC number from a DD Brassiere, but if you were to look at the amount of work that goes into the engineering to achieve the fuel efficiency numbers, you- like me would be chuckling at these posts.

Just for a second think about this: the stock intake system (and exhaust) has been proven to provide enough mass airflow to support around 500 CRANK HP on pump gas. That would mean it can deliver around +- 50 lbs/min of airflow. Cruising down the road say on the highway will only consume about 25-30 (depending on speed) CRANK HP. That means we're only drawing in and exhausting around 2.5-3.0 lbs/min of airflow; 5% or 1/20th of the capability of the stock intake (and exhaust). Even if a better (less restrictive) intake or exhaust might make more horsepower at over 50 lbs/min of airflow, they are NOT making any difference at 1/20th of that flow.

Does that make sense? It should.

AtlasBlue2022 · Oct 10, 2022

Wow you guys are so serious.

AtlasBlue2022 · Oct 10, 2022

lol I said “no guarantees”

TMac · Oct 10, 2022

You shared information- and so did we. That's fair isn't it?

AtlasBlue2022 · Oct 10, 2022

Hahaha yes. Ok how bout this scenario, you’re cruising down the freeway at speed, no stop and go traffic. You’re making a hint more power. You’re engine doesn’t have to work as hard to do the same amount of work. Could it be possible that you’d be saving a bit of fuel in that aspect?

TMac · Oct 10, 2022

Just stop. Nothing you said in that paragraph makes any sense at all. If you're making more power, you're burning more gas- period! "You're engine doesn't have to work as hard to do the same amount of work". That makes absolutely no sense whatsoever. I'm not sure whether you're trying to be funny or are completely ignorant. I'm trying to be nice....really.

AtlasBlue2022 · Oct 10, 2022

lol ok take it easy

GearHead_1 · Oct 10, 2022

Again, I did not mean to offend. I only responded because I believe there are a good number of people that are out shopping for CAI's that believe this exact scenario. These threads can stay on the forum for a long while and can be educational.

If someone is buying a CAI, or exhaust for that matter, because they enjoy the sound, want to dress up the engine bay or like the tailpipes, I get it. Expecting to see HP or MPG increases should not be expected.

Most of us at one time or another have done this very thing, who doesn't like the sound of an aftermarket exhaust?

MikeyP · Oct 20, 2022

After I installed mine, I saw a roughly 50mpg increase. However this was only for about 100 feet as I coasted down the hill out of my neighborhood. When I was actually driving it obviously changed nothing as far as mpg.

There is no real drawback aside from it lightening your wallet a bit. Doesn't change MPG. I felt there was a little more power in the higher RPMs, but I'm talking slight, and that may be my butt dyno trying to be optimistic. This intake does have potential to add power, though it needs to be accounted for with a tune. I didn't notice any more noise, but my wife and a few other people have said the turbos are slightly more noticeable. If you're looking for more noise, gotta go with the FenFab.

I got it because IMO it looked better than stock and I just wanted to do something to my truck. Plus I know it'll add a few more beans when I get a tune.

NewTekBuzz · Oct 30, 2022

Wow, pretty shitty response for someone just being honest with their experience. Is this whet we can expect from “top members”? SMH

Toadster · Mar 20, 2023

no tune needed for this intake right? why isn't this CARB legal yet?
