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

[LiftedrubiconJT]

Looking for info on cold air intakes. I’ve search and it looks as they are frowned upon. But I’m looking for better mpg and sound, not performance. I see they do help with increase of air. Looking to buy either banks or corsa

Of all the reading I've done on here about them, the only thing they appear to do is alter the sound and allow more dirt in through the filter. If I was ever to install one, I would put in the Mopar unit so that any future engine issues could not be blamed on the third party air intake.

The factory air filter unit works well. While it can be tempting to add one because they look cool the factory unit does a much better job of filtering dirt especially for off road. MPG gain really null if any there's plenty of write ups for this.

The best thing you can do for fuel mileage is a hard bed cover. You'll notice a difference immediately.

The OEM's fight for every tenth of an MPG. If better MPG was as simple as adding a cold air intake that flows more freely, they'd have been foolish not to do so. They hire the brightest and the best from engineering schools across the nation. Like said above, less intake restriction comes at a price. That price is more crap running through your engine.

If the stock intake is capable of flowing enough air at 6000 rpm, it's certainly not a restriction at cruising RPM. That's what matters when you're talking MPG.

Is anyone familiar with this?
2020 Jeep Gladiator Genuine Mopar Engine Air Filter - High Flow

Part Number: P5160245AA

It is an OEM part, but the "discounted" price is over $97. Looks similar to a washable K&N, but without the oil.

Less surface area than the factory one. I'll keep the OEM filter. You stomp on the loud pedal and it immediately revs to 6000 RPM it's not restricted.

I had a CAI and loved the growl it gave the engine, but can safely say I didnt notice any MPG increase. I DID however notice that while accelerating I would have a random rapid low whistle around the switch from 2nd to 3rd gear. Turns out the OEM intake has sound chambers on it that deaden the whine sounds. I ultimately switched back from the CAI to stock. I miss the growl and may look at them again after my warranty is up.

If you're interested Ill sell you the airraid one I have cheap so you can try for your self. Its just sitting in my garage taking up space.

I recently switched from a hard trifold to the soft rolling and actually didnt notice any change in MPG up or down.

The difference between a hard and soft cover is negligable. The difference between no cover and a cover is noticeable.

This has been proven to not be the case. There are no MPG gains from adding a cover to a truck of any kind. I got caught in a rain storm before I put the Bedcover on and had a rug in the bed of the truck. I drove through it thinking the rug was going to be soaking wet but was surprised when I stopped at a gas station to find the rug was barely wet, like only a few drops on it. Trucks are designed to force air over and around the bed and not down into it, which is pretty much why you can put stuff in the bed and drive and not worry about it blowing out unless it's sticking up above the rails. I saw zero mpg gains on mine after adding the Tri-Fold cover to mine

I'd say throttle response at take off would be your only benefit and I'm not sure how much of gain you would get there. It did make some difference on my JKU as far as on take off, I also would clean out the throttle body after every 3 oil changes and I did notice more gunk with the K/N CAI installed. I eventually went back to my stock filter and box. I found the Superchips Flashpaqs tune to 91 Octane got me the best results as far as MPG gains, particularly on my JKU, can't speak for the JT, but it made about a 1.5-2 mpg gain on the JKU. I never average over 15.5 in the JKU though, 2010 3.8 so go figure. Although I'd love to have the sound, I feel like I want to keep my JTs performance to higher level and not really mess with the setup they did with it, seems pretty good when compared to my JKU.

The OEM tunes do not get the best mpg...I do not have a CAI, but I do have an aftermarket exhaust and the Pulsar Tuner. The tuner economy tune added 2+ mpg over stock consistently. Exhaust helped in climbing and the need to downshift (6 speed manual transmission).

Which cover do you have? there' s a MOPAR tri-fold for sale that I'm considering, price is pretty good and I want one anyway.

I got the Tyger Tri Fold cover. I paid $163 for it at the time it was on sale on Carid. It's around $200 now on Amazon. I absolutely love it. Took about 5-10 minutes to install it and less time to remove completely if you need to use the whole bed.

I agree that there may be areas of the tune that can be improved upon performance wise and MPG wise. There always is. I'd be willing to bet my vast fortune (in nickels, dimes, and quarters, it would fit in a #2 washtub) that the resulting tune would either be potentially harmful to the powertrain or nowhere near being 50 state legal from an emissions standpoint.

A chuck in a truck with a laptop connected to your ECM is all fine and good. He doesn't have quite the restrictions the Jeep guys have when it comes to ECM tuning.
