What CAI can be used for a PW that gets dirty off road?

It appears that the "prospector" Rams have a water snorkel.
You may want to look into them, plenty of pix online!
These look like they'll raise your water fording level, depending on underhood waterproofing of course.

My 2015 PW gets 16 - 16.5 mpg running 60-74 MPH on the hwy. Once I get to the Texas border, the speed limit goes up to 75 (so driving ~80 to keep up with traffic) and lots of fluctuation at every town along the way, so lots of decel/accelerate betwee 45 and 80. Under those conditions mpg drops to 14.5 - 15. Around town it's somewhere around 10 - 12, depending on how much beltway driving vs using side streets. Stock engine, original tires at 55-60 psi, and not very aggressive driving and coasting to stops instead of waiting until the last minute and wearing out the brakes....


The mpg difference between 70 mph and 80 mph is about 2mpg. Probably due to the greater impact of aerodynamic drag at higher speeds and higher rpm.



My $.02.

Well, the PW has 2" more suspension and another ~2 of tire. That's a lot of drag regardless the gears. That also translates to gear searching with bigger tires or pulling a load.

You can subscribe me to the theory of these trucks needing deeper gears. The transmission gearing is right for a Cummins, but it's all wrong for a gas burner. That's why the 6.0L GM always seems to do better in towing challenges on TFL Truck etc. You're looking a a transmission that's suited to a gas burner. 4.03 Vs. 32.23 for the first gear is a significant difference. With 4.10 ring gear in the ram you get. 13.24:1 and with 3.73 ring gear in a GM you get 15.03:1. So you need 4.65xxxxxx to make the 3.23 work as well.

Yeah, What Craneman73 said. How's the mileage on the new 8 speed transmission for a Power Wagon?

I have seen a comparison test between the 2500 and power wagon at around 16.4 mpg with the 8spd.
