If a change in the intake could get 20% more mpg then ram would sell them that way.

Exactly.

Hey, it's totally possible. It was uphill on the way to the install and downhill on the way back!

I had the same thought, but fact is it did what it did. I wonder if something else isn’t controlling the design issue, some perceived epa benefit achieved by the clunky grid heater design. Only Cummins knows.

Monster and cold air intake. Immediately boosted mileage 4.7mpg day of installation on the 80mi drive to and from the shop on my 2023 2500 Ltd mega That’s 20%+. Very happily surprised.

Hand calculated? You can't believe the display as you have thrown all the factory calibrations out the window now...

Don't go off the dash, this is after I tuned my truck. No way this truck will get 26.6 mpg, always hand calculate. This is after a 30 mile highway run. If I remember right this tank came out to 21-22 hand calculated.

Of course its not hand calculated. Its the dashboard system so the 17mpg can certainly be off, as the 21.7 can be. Point is that whatever the dashboard algorithm error, it would be basically static. Its the same going 80 mi to the shop as going 80 mi home from the shop because it wasn't touched. Only physical parts were changed and the differential was 4.7mpg.

Road grade, wind, traffic, ambient temp, and road surface can all play a role that would induce that type of mileage change on the same truck on the same day without any hard part changes by going 80 miles one way and turning around.

The OEM intake is already a high flow CAI, and at cruise speeds there isn't enough flow to effect mileage. The only potential benefits from a different intake are at high boost and high rpm use. Even then the OEM CAI has enough extra flow to support 500+ rwhp without any appreciable restrictions.

The OEM intake is not a "high flow" intake....and your ideals on aftermarket are nonsensical.....not to mention half of you can't figure out which stock air filter to use....

Its the same road, so grade and surface is same. Not much wind either way. About same traffic both ways. Temp is maybe 5–10 deg different, abt 45 in morning, abt 50 on ride home.

Aftermarket parts have a purpose when they are warranted for the application.

The OEM CAI flows a lot more air than is required for stock tuning, that’s hi flow.

Unless the start and end point are the same elevation and any altitude changes are mirrored along the route then grade won’t be the same.

@AH64ID, save your key strokes, there are some folks you simply cannot convince.

Your post above summed it up 100% when you stated there are gains to be had but it will only be in high boost and high RPM scenarios. A truck moving at 65 mph down the freeway WILL NOT pick up any power or efficiency from changing the intake. The intake is flowing such a small amount of air there are no gains to be had for everyday driving scenarios.

If you want to reap the rewards of these aftermarket performance parts tune your truck, slap on a bigger turbo, and go visit the local sled pulls.
