Check Engine Light after Cold Air Intake

[MaverickDragon]

That would be true if the air WAS colder, but in most cases, it isn't...

The "cold air" way back in the day was from the front of the car, where most cars for decades now get their combustion air from, rather than from a tin can on top of the engine..

The new induction system doesn't chill the air, so at best, the only potential reduction in temperature and increase in density would be from the difference in routing the tubing vs. the stock config.

Considering that the factory induction system is plastic, which is an insulator, how much reduction will there be in temperature and a corresponding increase in density to the air running through from a short run of plastic, vs. a different run of plastic.

Likely, not much, considering that either induction component will live under the same hood, and a lot of air is traveling through the engine compartment, making the temperature homogenous while driving, which minimizes any potential beneficial effect of the intake plumbing routing.

After going through the turbo and then the intercooler I doubt there would be any difference. A larger intercooler may be the better way to go.

That too.
I'd like to see some data on the difference in temperature and air density between a stock and a "cold air" intake system.

The advertising notes that cold air is more dense, which is true, but considering all the factors involved in achieving that, and nothing that is obvious to cause that change, let alone to prove that it happens, in my opinion it's highly likely that there is a negligible difference in air temperature or density delivered by the aftermarket intake compared with the stock intake.

If there were a benefit, it would show up on a dyno, and hopefully not one that is contrived.

Regardless, in this case the Maverick consistently doesn't like the intake, so why waste money on a solution that is proven to be a problem....

Cold air with dyno. I guess it's possible

What a cold air filter does: makes the engine louder so it sounds faster. That said, the car will train itself using Mass Air Flow and Air Inlet Temp sensors to fix the mixture. Unless you hit a hose I don't see how the 2 are connected.

Just as good for speed and mpg is flames for the side. While we're at it, 90% of a new tune is ramping up your throtle response the opposite of econ mode so it feels faster, like a 90s GM V6 that hopped off the line when you touched the accelerator. Without boosting the turbo pressure you aren't getting more air in the engine and you need more air to get more power.

It's all relative to the ambient air temperature.
If the intake air is coming form outside the engine bay it will be cooler than the air around the engine and will help the intake charge.
When dyno testing an engine there is a correction factor that adjusts the the results to a standard temperature of 69°f and a barometric pressure of 29.92 inches of mercury at sea level.
An engine tested at 90°f will make less power than one tested at 45°f.
The compressing of the air by the turbo does increase the air temperature, this is the reason for the intercooler, which uses ambient air to cool the compressed air.

Hey everyone, I started getting a check engine light on my 23' Maverick after installing the Afe Momentum GT Dry Cold Air Intake. I got the code P04F0, EVAP System High Load Purge Line 'A' Performance, after taking it to a shop. They checked all the lines and the purge valves and nothing was wrong, they also found nothing with a smoke test.

Any advice on fixing this would be appreciated.

I installed the same aFe intake on my Maverick without any issues. That said, after running it for a couple of months, I honestly feel like it wasn’t worth the money. Just my humble opinion. Here's a video I created during the installation on my Maverick. I hope it's useful.

FWIW, I run a scangauge 2, and have my AIT set as one of my home gauges. Watching the ambient on my cluster, and the scangauge, there's usually only a 2-3 degree difference on a hot day tops. On cold days its 1 degree. I'm not sure how a "cold air" intake would benefit unless you're pushing big HP and need to flow more air. Even then, its not likely to be a temp reduction over stock.

Id rather spend on tint, that will actually cool something down, or throw a little more $ with it and upgrade the FMIC.
just my experience.

My previous vehicle was not a turbo, it was a Hemi Charger. I changed the rear end to a lower geared LSD differential and then got a performance tune to optimize shift points as well as high octane fuel. After many data logging sessions the tuner sent me a tune which I was very happy with.

I then added a cold air intake which was plumbed to the exterior of the vehicle, repeated the data logging and sent to the tuner. He said he couldn’t see any difference in the logs and to stick with the tune I had.

That was my first and last foray into the cold air intake market.

I guess I’m suggesting you return intake to stock, hopefully get rid of code and take solace in the fact it never gave you any performance gains in the first place.

Remove intake and put stock back on

Contact AFE. They will send you an updated part to resolve this.

Have the same issue. With the AFE intake installed I get the same code, P04F0. Cleared the code and CEL came back on a few days later. Removed intake and put stock back on. Cleared the code again and the light has been off ever since. This is not a coincidental sensor failure. Seems as though there is an issue with this design or a custom tune is needed to keep the light off. Emailed AFE today and am waiting for a response.

Did you ever get an answer back? I’m having the same issue.

A "Cold air intake filter" is exactly what the name implies.
The intake air is cooler and therefore more dence which should produce more power.
It does not necessarily allow more air flow.

Ok so where is the condenser, where is the cooling unit ?
The air getting pulled in my stock intake is outside air.
The air the so called cold air intake gets is cooled by what method ? It’s sucking In The same air at the same temperature as mine.
Right ?
Somebody take me to school, I’d like to know.
