AEM Air Intake on 2019 Cruze? Will tune increase power?

I see a lot of people saying that cold air intakes make no difference in performance or fuel mileage. I do believe this as you are just pulling in warmer air since there’s no cover over the filter. I was wondering if anyone has had their tune adjusted for their intake? I have the Trifecta tune and it’s amazing, car pulls like crazy and I’ve had that tune for about 6 months. There must be gains if you get re tuned just for the air intake, correct?

This has all been said a thousand times, but....

Your car already has a CAI. EVERY aftermarket CAI will actually put warmer air from the engine bay to the turbo. Most aftermarket intakes are actually short ram warm air intakes.

And yes, to get any benefit at all the choice of intake is taken into account for the tune.

IMHO, if you want to make the better use of your money here is what you do. Withdraw the money you would have spent on the intake in one dollar bills. Then burn them in a bucket to stay warm for the night.

The sound tho… it’s addicting lmao

who says you have to use the oil?? use the K & N dry

That would ruin the point of it, the k&n lets in more air flow so it needs that oil to catch extremely small particles. Without being oiled you’d let a lot of crap in that you wouldn’t want. The AEM is meant to be dry and that’s why it doesn’t let as much air through as an oiled k&n. AEM would have smaller openings to make up for not being oiled. You get less air flow but cleaner air which is a lot more important. It makes sense anyways. Manufactures recommendations are there for top performance out of the item.

Yes, you have pointed out exactly why the OEM intake actually provides cold air to the engine. All the aftermarket intakes let some of the cold air in and a bunch warm air from under the hood. Think of it this way, if the aftermarket intake flows more air, where do you think that air is coming from?
I could list a dozen reasons why keeping the stock intake is a good idea, keeping in mind it will support an extra 50 HP.

If you want a faster better sounding car, spend your money on the exhaust system.

I largely agree with you but I think you're also dismissing it to some degree. I'd have to test with a thermocouple in place but the aftermarket designs also isolate the heat/air with a gasket that seals on the hood. I doubt it's much different than what's inside the stock air box. But I'd happily admit if I'm wrong there.

I think beyond anything else what aftermarket intakes do that stock intakes don't is introduce some sort of high flow air filter to the mix. That's where the power usually comes in, not the temp difference imo. You're just jamming a bit more air in their and the ECU compensates and squirts a bit more fuel, adjusts timing, etc. You probably get the same boost in performance for a 10th of the cost if you just buy a high flow factory filter.

Of course if you're going for the look and sound of an aftermarket intake, they're pretty harmless from my travels.

Oh I agree. That video was great thanks for sharing. Love grumpy old Banks haha.

But I don't think the 2 intakes offered for the our specific car are that bad. They're located in the same location as stock, they also do isolate the heat with a divider and gasket, and include a higher flow filter.

I think the negatives that are all over that video are negligable in this case. But again, I agree in principle completely, I'd just love to see more more data on our cars specifically because I don't subscribe to blanket statements like "open air intakes are bad" or "fords stink" etc.
