Cold Air Intake produces a 41 Horsepower Gain for 2025 Ram?

running a K&N is pretty much like not running a filter at all.

I love these posts, because they're mostly nonsense. Properly maintained they filter just fine. I've ran one in my off road rig for almost 13 years now, 150k miles on it, never an issue even in silty dusty conditions. UOA's always come back clean and free of silica.

The problem is people improperly oil them.

I've had more K&N filters dust an engine then you can shake a stick at,and i don't go off road. Their oiled filters are the worst. You're better off with a non-oiled filter then an oiled filter

This has been talked about endlessly on this forum.

These engines are computer controlled. The air is metered. It's only going to allow so much air in regardless of what intake is installed. You are not getting any performance increase without a tune.

how is the air metered? I know the Hemi's are SD tuned which means there is no MAF. The air is not metered and is guessed by the ECM based on MAP readings. It would be @$$ backwards for FCA to go MAF on a turbo or boosted motor being that everyone switches to SD when they boost for good reason.

I had one took it off. All it did was make it sound like when I was a kid and we flipped the cover on the air cleaner. Sounds cool but actually lost a little mileage. Didn’t go as far as a tune. Actually the flow through muffler added some mileage. Didn’t do a true dual just the muffler.

That number seems a bit high, on a boosted application any restriction on the inlet can affect output substantially (more so with blowers). If they are able to get cooler fresh air with less restriction you could see some decent gains on a boosted setup. Lowering the IATs alone can net a gain without increasing flow specifically (we don't know how much retard they have built into the IAT vs timing reduction tables) but it could be 5 degrees easily given how much boost they run. If you can grab 20-30* cooler air that's less heat that needs to be removed from the A2W intercooling, denser charge, less timing being pulled and increased power. To get 41hp on a 420hp motor thats alot and would need some serious magic to reach power levels as much as adding 1-2lbs of boost. Maybe 30* temp drop, increased flow and a few degrees of timing saved "could" net that.

The hurricane uses MAF.

The gen 3 Hemi uses a speed density system to calculate air mass and adjust timing. It does this by engine speed, intake air temperature and pressure. Theoretically, if you could ram cold outside air directly in to the manifold you "might" see a slight benefit, with a caveat. But the fuel mapping will not have changed, so at most you'd see optimum conditions the fuel map would allow. Which means you would not see a single HP over stock as that is what the stock programming is programmed to output. Otherwise you would be in a lean condition or pulling timing.

This is why tuning is needed to make use of bolt on's. Otherwise you're just making your truck run at 395 HP the best it possibly can.

There isn't an aftermarket CAI that will deliver 20° to 30° colder air than the stock set up.
Probably the best recourse to get colder charge air temps would be to relocate the factory intercooler radiator and add fans to cool the intercooler glycol as cold as outdoor ambient will allow. Maybe rig up a water spray for intercooler radiator during the hot months. Take it to the next step and spray a water/methanol mixture to cool the charge air.

Nitrous and turbo's go hand in hand,wonder how one of them would perform with a 75 shot,lol

K&N is claiming an HP and torque gain as a result of their Cold Air Intake parts. The RHO has an OEM version that does not produce any gain. I believe they said it moves the HP/Torque down lower on the RPM curve. Do any of you have this installed? Does it work? Is there a danger adding too much HP/Torque? See the claim below.

The ONLY place a cold air intake makes power is on a dyno with the hood up and a shop fan blowing into the engine. It is the biggest shiny bobble that makes the most money off of ignorant people.

The moment you close the hood your cold air intake becomes a HOT air intake because it pulls air from the engine compartment and not from inside of the fender well like the factory setup. The fatory, and i do not care if it is Dodge, Ram, GMC, Chevy or Ford, paid some pretty smart people to design an air intake system for your truck that will deliver all of the air it needs and then some. Put a cam in it, stroke it, forced induction, now, maybe the cold air intake MIGHT give you more power because the engine now requires more air. But if you bolt a cold air intake on a mostly stock car/truck, it not only is not going to give you more power, it is likely going to rob power from you, especially in hot summer days because of where it pulls air from.

If you like the shiny and you like wasting money for the cool guy look, go buy one. But it is not going to make your truck run better or give it more power.

Do you want to know where a lot of trucks lose 50hp or more from a bolt on? Big tires. rofl, the bigger, the more power it takes from your motor.

Might as well throw on some water injection while you're in there, lol

Definitely will want an E85 tune if your gonna spray!

 

[NCRaineman]

Back in my boosted tuner car days some guys sprayed nitrous on their intercooler to lower air temps. Seemed to work pretty well and a lot safer than running it in the engine.

 

[Rlaf75]

Read the fine print because there's an * next to both HP and TQ. There must be some extraordinary circumstances to achieve those kind of numbers because that an awful lot to gain

Or 100+ octane,lol.Not much in the way of E85 up here,so you'd want to pull some timing to use 91 or 93

Nitrous creates instant exhaust heat,so a turbo spools up faster. I ran nitrous on a turbo car back when i was a broke ass kid,as it was a cheap/easy way to combat the boost lag the early turbo's had

 

[Compu-Doc]

Even if it doesn't make J S for extra HP I still like the hardware I put in when I first got my Hemi

Thank you for enjoying my post. i stand by what i said. junk. But Glad you like them. may you continue to enjoy your purchase even if its questionable.

Also like said, people don't maintain the oiled filters properly either.

Yeah, we did quite a few for customers when I worked here, as Archie said - those were the days - I think I'll cross post this over to the Random car pic thread
