Cold air intake ?

I have a 2013 Moab . Looking to get a cold air intake with a new exhaust. If I do this with it void any factory warranty? Is it even worth the $1000

I have a dual "cat back" exhaust and I like the look and the sound but it does nothing as far as performance which I knew going in. As far as a CAI, I don't think they are worth it for a JK and I can't think of one thing that's positive for installing one on a "JK". Opinions vary on this. I believe you're better off with a good "dry" paper filter in the stock box. A snorkel set up is different.

I just ordered a cold air intake that will actually provide significant power and fuel economy improvements:




A little more than $1000 though...

Reusable filters don't filter as well as factory paper filters, there have been a few studies and unless things have changed a lot this is a fact.

Will it destroy your engine? Not likely. Will it shorten the life of your engine? Definitely.

On an engine that has restrictive intake it may help performance, so far I've never seen any dyno data for before and after CAI on a JK.

EDIT: of course the turbo above will certainly give some performance improvement ;-)

Thanks definitely want to get the same exhaust , looks like its easy to install.Their is a lot of positive and negative feedback on a lot of other post about the cai. I know it's only a jeep but if it with damage the engine it's not worth it for the little you would get in return . Thanks for the feedback

I have done some pretty good tests with my Jeep dealership on CAI's and they don't do crap. Do some searching on this site and you will see the results.

Look more closely at the picture I posted. There's a turbo in there. You just highlighted what I thought was amusing: that turbo kit looks just like a plain old CAI kit if you just glance at it quickly

If you want the sound and the look....by all means do it.

If you are looking for a performance gain, save your money for gas (unless you need every ounce of HP above 4000 rpms you can get). Will it void your warranty? Depends on the dealer..and the warranty would only be impacted by what could be traced to the CAI. Of course, the engine is a big item to lose your warranty on.

Besides, outside of a snorkel, there really isn't a true CAI for a JK.

CAI is more like WARM ENGINE AIR INTAKE.....CAI does absolutely nothing for HP/Fuel Economy...just makes your motor sound more throaty! You will get more boggy performance on hot summer days in traffic & wheeling with a CAI setup!

Snorkel is a better CAI system that actually draws cooler outside air vs hot engine heat.

A general comment on CAI's. I did a bunch of testing with my 99 drag car - basic results are below (accomplished by monitoring the mass airflow sensor):
- On a dyno with no external air flow there was absolutely no difference all the way to wide open throttle
- On the road, below 40/50MPH - just a touch of difference.
- On the road, above 50MPH - you could start to see a measurable difference. Basically it took some "ram air" effect to allow the CAI to really do anything.

As always YMMV!

There is no ram effect. You're almost certainly not reaching the speeds necessary to force additional air down that tube in a Jeep. Wind blowing across the filter isn't doing it...air is drawn in by the engine's needs (an engine is just a big air pump). Air pushing in on one side of the cone filter just decreases the amount of air passing in through the opposite side, until your wind speed actually outpaces the engine's draw. Which A-you're not going fast enough to do, and B-that wind force is broken up because your filter is in the engine bay anyway.

If there were any real ram effect, why does almost every "ram air" production hood in history actually have a plug? Why do actual race vehicles usually have the induction point at the back of the hood? The answer is A-there isn't one, and B-air pressure coming down off the windshield is higher than anywhere else on the hood.

I've got a quote somewhere from one of the big names from GM Engineering from the muscle car days (Lars Grimsud) about how worthless ram air hoods and intakes were for performance. Exclusively a marketing thing.

A $100 CAI is a waste of money. A $1000 CAI is a felony.

The $1000 the OP mentioned was the total cost of CAI + exhaust.

Try one of these

5PSI Electric supercharger Turbo Add Horsepower Torque Intake for Jeep | eBay



It says "Stage 3 High Performance", so it must be good.

The tube duct taped to the gas tank added about 25MPH to the top speed and according to my uncle you could feel it start to hit around 80MPH.

This of course is a carburated... motorcycle.. and 2 stroke as well so YMMV

I was looking to buy an Airaid Intake for my 2010 auto JK 3.8L with 33 and 2.5 lift but after reading reviews a new intake does not seem the way to go. What would my best options be to improve fuel economy and/or torque?? And would buying a superchip be a worthy option?

I wonder if this Military Egipt airbox would help improve performance or if it's just for higher dust collection capacity, or both...

Put in a hemi? Seriously, it's not like the "old days" when you could put in a cam, new carb, tune/tweak and get good results. It may be possible to shuffle the power around, get more torque, etc from changing the programming but I personally don't think it's really worth it in terms of costs or results.

Supercharger or turbo will increase fuel economy when driven "normally". And they'll definitely give you an increase in torque/power. Turbo is more efficient than a supercharger, so it will likely give the best gains in both peak torque/power and fuel economy (Prodigy claims 4mpg gain when driven "respectably"). You'll never regain the cost of it in fuel savings over the life of the vehicle, but it's nice to slightly reduce a recurring cost.

Supercharger vs turbo is a completely different topic, which JeepLab will be addressing soon when it tests a Prodigy turbo and compares it to both RIPP and Magnuson superchargers.

A handheld tuner (Superchip, Diablosport, Bullydog) by itself will give you a couple mpg at most (if you run the fuel saver tune), or up to about about 25 ft-lbs torque gain (at some rpm; not necessarily peak torque gain) if you run the 93 octane performance tune, but you don't get both at the same time. What can't be put into numbers is how the tunes improve overall throttle response/feel at part throttle.

Uh....those are fighting words right there!



Yes, yet it is a different topic. I am surprised there hasn't been a comprensive thread on it specifically, but the debate has come up before. I just get my popcorn and watch the fireworks.

Yes, the supercharger vs turbo debate has happened before, but it has always been theoretical and based on vague generalizations, never any actual comparison between an actual turbo jeep and supercharged jeep. Can't wait to see JeepLab's results and thoughts.

I can back up some of my "fighting words". Here's JeepLabs results so far for stock, Magnusson and RIPP:






Stock:
175 tq, 189 hp

Magnuson (intercooler, 6psi boost):
254 tq, 282 hp

RIPP (intercooler, 7-8psi boost):
280 tq, 319 hp

Prodigy's published stage 1 (no intercooler, only 5psi boost) results:
335 tq, 317 hp

Stage 2 (intercooler, 9psi boost) results should be available by sometime next week.

Turbo is definitely more efficient

I won't be getting either one...but I would enjoy a good thread on it if there was quality (and unbiased) data. Seems like a good way to learn so new stuff...and it would be much better than another 2 door vs 4 door, auto vs manual, or hard top vs soft top thread.

Im currently testing a Corsa Performance intake, with a Donaldson filter, courtesy of GotExhaust.com. Mostly testing the filtration, however, the sound is very nice, and only loud at a certain RPM, otherwise, its barley louder than stock when driving normally. Intake temp has been running the same as the OEM system, and in some cases, on cool mornings, a little cooler. AFR's are similar to stock, MPG, etc. Im 500 miles into the filtration test, so we'll see how it goes. The Donaldson filter is a 100,000 mile filter, with some reports going as far as 150k miles, and still filtering.

as an old guy, i am amazed ho many of you treat the wrangler as a muscle car like we did in the early seventies. not trying to insult anyone, just not something i would ever have thought to do. o course if i worked for chrysler i would be showing this to the higher ups and making the hemi an option.
