Cold Air Intake for a new Mojave (2023)

[Shift Happens]

1. Is there really at least some benefits other than the sound? Does CAI improve fuel economy at least a little bit? Added 5-10 hp is not something I would feel, I assume.
2. Are they safe to install, assuming of course installed properly? Is there any possibility it can do damage to the engine?
3. Does CAI void the warranty? I know this one might depend on a dealer but I'm mentally prepared to lose the warranty assuming of course, CAI cannot do any damage to the engine

Seems like its been answered, but I'll throw in my 2 cents

1) Got no benefit from mine other than sound. Gas mileage hasn't improved. Certainly no horsepower gain. Engine revs high, but doesn't move any faster. I don't even get a "seat of the pants" improvement.
2) Mine is the same intake design as the factory box(Injen Evolution with dry filter), but has some extra slits on the top of the box. Doesn't seem to be able to draw in anything dangerous any more than the stock box
3) Could always keep the old one, swap back when bringing it to the dealer :P

After reading about them in depth, I’d prob avoid one on the one on the pentastar, as the intake noise isn’t all that great (my subjective opinion)

On the ecodiesel it’s a different story. I have the S&B and I’m seeing 1.5-2MPG improvement so far with 2 tanks of fuel….

I don’t think either platform will improve power…

Thank you, guys. Very helpful and informative. Based on what I learned here, I will not be installing any aftermarket CAI for now.

I am flirting with an idea of supercharging my Pentastar (Ripp most likely) but there is a lot of info available and I'm still reading on it. My point is that it seems like a part of the supercharger install, you'd typically install the CAI, so maybe that'd be a good time to do it.

Btw, I did own this ecodiesel in my 22 Ram 1500. Loved that engine! The only problem I was getting is "water in fuel" error would pop up here and there for no reason. It seems like the sensor on the filter was too sensitive...But man, with the 33-gallon fuel tank, I was getting over 800 miles of range on long drives. For me personally, the feeling of having a lot of range at any given time is priceless

Yeah I would imagine with the supercharger you might start to hit the limit of the stock air box. I imagine the stock airbox would flow 300ish HP, based on the filter size. My Stock Miata airbox will flow 230HP without any flow restrictions, so I didn't bother, on that vehicle.

The Ecodiesel seems to be sensitive to filters as they fill up. I am seeing 1.5 / 2MPG consistently better with the S&B intake... I honestly don't know if it's the intake though... my stock filter had 17k on it, and was quite dirty.

Yes, I do hear that upgrading CAI on a diesel is a slightly different story. But yeah, maybe it's just a clean filter

The stock air intake brings in cold air.
The stock intake provides more air than is needed for the proper air fuel mixture, so without an aftermarket tune to actually utilize more air and fuel there is no benefit to adding more air. You can bet that the engineers designed the stick setup to provide enough air for proper function with an end of life dirty filter, so there is already excess air available with a stock clean filter.

As far sound goes, I prefer a quieter engine, so maybe I'll get the Mopar. LOL

Keeping in mind that a dirty filter restricting air flow can mess with emissions - and that most of the time these engines spend only drawing in a fraction of the air they are capable of drawing in or even need.
One can figure the need for air just like we do on our performance vehicles - the engine is a pump. You can figure the CFM needed pretty easily (there are web sites if you want to figure it quickly and easily)
Unless you run these at high RPM and heavy load for extended periods, the air filter (and tube) isn't going to be a restriction on these stock engines.

I imagine the stock airbox would flow 300ish HP, based on the filter size.

It's about CFM - and how many CFM a given engine needs. Not how many HP it will support. You can only use that when comparing identical engines - but even then, it's not a good way to calculate air needs. I can boost HP and not change air flow that much, and i can boost air flow and not gain a ton of hp after a certain point.

The filters below are supporting a bored 360 ci engine (more like 367 now) putting out close to 400 hp - so you would figure 367 cubic inches at xx rpm would pull yy cfm and figure air filters and carburetion for that.
The 3.6 liter is about 220 cubic inches. A fraction of the engine below.

Of course the throttle body and intake manifold come into play in the 3.6 engine

Thanks Shadows, You are right, although I imagine commonly Horse Power and CFM needed are closely correlated due to air fuel ratio's of gasoline engines not being extremely wide, and overall engine efficiency, diesels are different as many diesels do not even have throttle bodies, and the Air Fuel ratios can be extremely lean, producing little power with a lot of air.

I have seen air boxes 'rated' in maximum HP, but yes really it's a measure of CFM air flow.
