I got my 2020 jeep gladiator about a month ago and the temperature where I live is 30’s/40’s at night 50’s during the day and I have noticed a lot of exhaust steam coming out of my tail pipe recently. Is this normal?

Yup - almost everything coming out is water vapor and CO2
It will vary with how hot the catalytic converters are, how well they are doing the job, but what you see will be dependent on air temperature, relative humidity/dew point of the air, and other factors.

As long as it's not "A LOT" and doesn't have a nasty smell to it, that is.

I also have a cold air intake on it. Would that affect it any? It rolls out pretty good when idling but it just disappears pretty quick

Burning fuel produces water molecules. Until the exhaust system is hot enough to totally vaporize the moister, it'll show up as a white cloud.

No, those really don't do anything at all other than sound cool.

When there is a White cloud that lingers and smells like coolant then it's a problem.

And it's a smell you can't compare to much else .....

somehow that does not surprise me.
Well, you were the one that said the CAI looked cool. Do you really open the hood and stare at it?
Does anyone really care how it looks (well, apparently some do! HAHA)

The hood on mine gets opened only for occasional fluid checks, belt check, that sort of thing, otherwise, it's wasted energy. CAIs are a total waste of time and money unless you like the sound.

Ironically, I find the 2025 3.6 sounds louder under acceleration at around the low 2,000s RPM than any other Jeep I've owned, and I wonder - what did they change? Perhaps the tune?
The 25 has more of a heavy-breathing intake sound than any of our other Jeeps have had.

I have a CAI on my 2015 Camaro SS, and the sound alone was worth it (I got it for a great deal, though). It gives a lot deeper sound up front.

Now, on those cars its worth an additional 5-15 HP IF you tune for it. Eventually, I'd like to add long tube headers and have the local shop do their magic. The CAI and LT's together with a tune are worth around 50HP on my L99 car as they are reallllyyyy held back stock.

It wouldn't be nearly the impact on a 3.6, and I wouldn't spend the money for sound OR looks.

It’s normal, water is a byproduct of combustion. The hot exhaust is condensing when it hits the cold air.

Oh, like the streaks we see in the sky behind a 747.
