Post up your cold air intakes and experience? Looking for better mpg

[ShadowsPapa]

I just cant get over my mpg difference between my 20’ GPEC2 vs my 22’ GPEC5 3.6. Both similar lifts, steel bumpers with same winch, both running the same tonneau covers, 20’ jeep intake vs 22’ mishimoto and both with 2.5” and 3” straight catbacks. I was over 20mpg on my 20’ vs 16-17mpg on my 22’. Yes my Mojave has 4.10’s vs. Sport 3.73 but that should help with 35” tires. Its a head scratcher for me. Same exact driving, nothings changed.

Weight matters. Mojave is heavier.
Similar lifts - or sitting at the exact same height?
Width will matter some for frontage - the exposure of the fronts of the front tires, etc.
Tire weight and size matter as well.

Mojave is heavier yes but it cant be by much, its no Rubicon. Tires are 4lbs heavier per tire but my front bumper is 25lbs or more lighter currently. Im just having a hard time with the mpg change. 1 or 2mpg ok, but its like 3-4 different. I even reset my mpg while back, same. Sitting at just shy of 17mpg. Lifts are nearly identical, 1”f .75”r vs 1.5”f .75” on my 20’. Actually take offs from my last JT. I think the tuning is different, my 22’ does feel peppier but that could be the 4.10s.

How many miles? My 2020 didn't do great until about 7,000 miles then the MPG went up noticeably.

9500km. So 6000 ish miles

FWIW, I had a Volant CAI on order…3 months on back order. I cancelled my order and picked up a k&N box\tube setup with a Donaldson filter.

My mpg’s have not gone up or down so far. About 500 miles on the setup. 6mt with 4.10’s and 285/75’s. Getting an average of 19.1 city and 23 highway. will tell you it is loud AF!!!

wanting to see what it does when the temp drops outside.

Same for me and the Injen one I installed. No changes in MPG. Mix of 75mph/60mph/45mph driving to and from work, averaging about 17.3mpg from full to empty.

Thanks! The video does not do it justice, it is pretty loud when you get on it. Cruising speed is normal which is what I was hoping for.

Are you running all stock exhaust with no deletes?

Yep, all stock exhaust. It’s pretty damn loud when you get on it, which I’m happy about for two reasons. The first is, now I don’t have to go cut the exhaust off and mess with anything. The second is it makes driving a stick more fun because not only does it sound good, you can actually hear where you’re at RPM wise if you got music on or a lot of wind noise.

You guys just don't know how to drive. Lol. Always drive downhill with the wind at your back.
