Cold Air Induction?

[1stindoor]

Quick question for any of the 2500 6.4 Owners. Have any of you installed a cold air induction on the 6.4 and had any noticeable improvement? I've had them before on my GMCs. But my last Ram was a 2018 2500 with the 6.4 and I had a K&N air filter, which seemed about on par with my previous CAI system on my GMC. A K&N will run about $100. I found a nice CAI kit from S&B for $350. I don't want to throw another $250 if the performance will be about the same. Appreciate the input.

It's not really worth it to even put in a K&N filter, honestly. The stock filter flows more than the engine can pull in. It also doesn't need to be oiled, so less chance of screwing up your MAF sensor.

Thanks for the input. I'm not "itching" to spend the extra money either. On my 2018 the only "mods" were an exhaust, the air filter, and a pedal commander. I still have the commander, but haven't installed it yet. Have an exhaust ordered. And I swapped out the factory Firestones for Nittos.

Agree that cold air kit is a waste of money. Also, K&N filters do not filter as well as the OEM paper filters. If you use it in any kind of dusty environment you will find fine dust AFTER the filter element that you do not find with OEM. Also, oiled filters have been known to mess up the sensors on diesels and the oil can contaminate sensors on the gas as well.

agree with all the comments above. A stock intake will flow more air than a stock or mildly tuned engine will even need

1) K & N oiled, no no no.
2) Got decent tires, outstanding.
3) Check yer Pedal Commander with the web site as there is a difference in which one you get on a 1500 2018 vs 2019 5th Gen. May be the same for the one you have on yer 2023 from your 2018, so something to verify.

I checked the site (I'll double check though). Pretty certain it's the same one, PC31. Appreciate all the input folks...so does my wallet.

OK, on 1500's Classic is PC 31, 5th Gen is PC 78. But 2500 may be same one, as I am not familiar with the differences in the 2018-2019 2500's. Good luck on all your mods and driving.

Looking it up on Amazon and the PC site:

PEDAL COMMANDER for Ram 2500 & 3500 (2019 and newer) (4th & 5th Gen) Big Horn, Laramie, Limited, Lone Star, Power Wagon, Tradesman (6.4L 6.7L) Gas & Diesel Throttle Response Controller - PC31​

I removed a nice CAI and upgraded/modded my 5.7 to the 6.4/EcoDiesel lower airbox and intake horn with the stock MOPAR air filter for the 6.4/EcoDiesel.

Much better flow, and cooler air from the already existing system.

I can sell you some plaid paint

I have a 2019 2500 6.4, and it takes the same air filter as the Cummins does. I can guarantee the hemi isn't pulling in as much air as the Cummins is while being boosted to 30+ psi, so IMO absolutely no reason to install anything different on it in stock or mildly modded engine.

What no way guys I installed a CAI intake on my truck and made big gains of HP & TQ ( HP = my wife's mouth yelling at me how much I paid for it ) ( TQ = her foot kicking me in my butt ) LOL they are right save your money and use it for something else

So I hooked up my PC31 this morning and just completed a 80 mile trip. No issues.

Snake oil on modern engines. The air is metered and computer controlled. The engine is only going to allow what it needs to run with applied tune. Stock air box and filter flows considerably more air than the engine needs.

CAI's make cool intake noises though. If that's all you're interested in.

If you want one I have one from Spectre for $100. It is brand new

Yes depending on the year. You air filter fits the Cummins prior to the '19 model year. The '19 and newer Cummins uses a different air filter and people have been having DPF faults if the wrong/cheap filter is being used. Also the '18 and older HD 6.4 Hemi shares the air filter with the DS body EcoDiesel.
