2025 3.0L I6 K&N Performance Air Intake System

[Nethellum]

There is a lot more to engine cooling when driving down the road than just the cooling fan. When you are above 35-40 mph, the airflow from speed , is more than the electeic fan will ever pull. Plus the airflow through the engine bay that gives some air cooling assitto engine. Plus, by the time the electric fan kicks on, the PCM is already pulling timing due to coolant temp.

Now, I'm not trying to justify the HP claims by cai manufacturers. I've already said they skew the numbers. But you never want to dyno a vehicle, with the hood closed, unless you are in a wind tunnel that can create the same wind speed as driving down the road.

Just watched a few videos with dyno runs hood up and hood closed.

I installed the K&N system on my '25 Limited but thinking about putting the stock intake back in. My IAT (intake ambient temp) sit at 200F according to JB4 app! That doesn't feel right... I wonder if there's a limited > RHO hood conversion to help out.

That doesn’t sound good at all. Would have to believe timing is seriously pulled at those temps.

Were you watching IAT’s before the swap?
Would be super interesting to compare to stock.

Engine was running fine actually, just wish I noticed the high temps earlier...

I'll check the jb4 app after putting the stock intake back in and report back.

Yikes, that is incredibly high. Can't even imagine what that looks like under a real load over 20psi+

Is the it's sensor before or after the turbos? Are you sitting still when reading these temps, or cruising down the highway?

I'm not exactly certain which sensor or location yet. Once it reached those temps, it didn't come down, even on the freeway. Thankfully haven't put more than maybe a couple hundred miles on with the new intake and mostly short trips.

It didn't get to those temps right away, might be after driving a bit, making a stop then continuing on.

Curious what others with the K&N are seeing...

Edit: All of my temps were fine on the dash as well.

OEM intake is back in, temps are normal (<120) after making a few stops and freeway time.

Here's where I think the IAT sensor is.

Also, look at the design of the front grill. It's blocked off and the intake inlet is a hole near the radiator. I think the OEM design uses the sealed box to actually suck air in instead of relying on it flowing in freely.

IMHO, DO NOT put this on a RAM that does not have an air inlet in the hood, and the only one that does that I'm aware of is the RHO.

We'll see how the S&B works when they release it, they have a custom inlet design instead of relying on the OEM hardware.

Edit: I plan to investigate how to modify the hood and or rework the air inlet but honestly, the OEM design seems pretty good...

Great post, from what it looks like on S&B's site they plan to use the OEM inlet design.

It does look like it has an optional window so its sealed as well.

In that case I have to ask then, what's the point over OEM? I guess you could argue that an (i assume) aFe filter is better than OEM but other than that, it's essentially the same design. Looks nice though...

Run S&B on my Jeep, sounds much better - so that is enough for me. As for function, I'd offer a better overall filter.

It’s for when you want hotter air filtered by a screen door.

The sound is nice though.

Sounds about right from my experience.
