You could always spend an extra 50% and have a snorkel

$250 for an AEM brute force, or a snorkel for $390 shipped. HMM.

TBJ great photo, what do you think you are a boat that floats?
More brave than I would ever be. If you are going deep like that make sure your breathers are extended up, all of them!
How much belt squealing you got after a run like that, fried an alternator yet? Water inside?

No broken parts, little water came in under the doors. Breathers are extended First "mod" ThunderbirdJunkie did to the KJ.

i have the k&n. its way better than stock on the whole rpm range and it takes less pedal to hold high speeds. tons of pick up compared to stock IMO from what i feel in my jeep. there is a noticeable difference to me. i also tried another intake design that was trying for a true cold air intake set up, but it seemed to kill the power.

Just my 2 cents worth, but it would seem than the increase in airflow comes at the expense of decreased filtering capacity, allowing more dirt to pass into the engine.

On the street, that's not a good thing, but not so critical. In an off-road evironment however, the amount of dirt drawn into the intake is multiplied vastly.

On my VW powered dune buggies, we ran K&N filters, but with pre-filters and socks over and around the main filter bodies.

 

[ThunderbirdJunkie]

Oh honu...if only you've seen the previous storms created by those very statements in the past.
*BRACING FOR ANGER*

Also, honu is 100% right...
Remember the K&N ad about 10 years ago about old dude with the '70s Chevy pickup?
I'VE GOT 700,000 MILES ON THIS TRUCK, AND THAT FILTER HAS OUTLASTED FOUR ENGINES!

Sorry, but if you've been through four engines in 700,000 miles, there's something wrong.

Good ol' paper filter for ThunderbirdJunkie!

^^^ LOL I wonder why the engines didn't last very long

Pro tip - K&N air filters let lots of crap go through your engine

Plus that sludge that you have to put on them.

It's a Jeep, doesn't need to be a tenth quicker. It needs to last long though.

I just use Fram air filters. JMO.

So is it better in the long run not to get an aftermarket air intake?

 

[mag03kj]

No! Well only if you want to!

In my honest opinion, yes.

Again, just my opinion... but what I've done is to "clean-up" the airflow path of the stock intake. What I mean is that most intake tubes, running from the airbox to the throttle body, have a corrugated, flexible part. I think this causes turbulence in the airflow.

What I've done on my Magnum is cut out the flexible section and replace it with a thin wall, aluminum tube. I also swapped out the stock R/T intake air box and tube for an SRT version... 4" to 3 1/2" as opposed to a straight 3 1/2 tube. This allowed for a less convoluted airflow into the intake system.

Personally, my butt-dyno hasn't registered any more horsepower, but the throttle response seems a little crisper.

I'm certainly not criticizing those who've switched to CAI's, but I'm a low budget guy, so cheap or even free gains are great.

Well I ended up ordering the aem brute force intake and I'll keep you guys updated !

Before I hijack this posting I'll comment on the air breather improvements.

I thought the improvements seen with the aftermarket airfilters was due to their increased area. Is it true that the K&N filters don't filter very well? that would explain the better airflow with their filters.

I like the idea of replacing the corrugated hoses with something smooth to improve airflow without replacing the stock filter box. Plus some of those aftermarket air filters can be expensive.


I've actually witnessed a YJ Jeep complete with a snorkel drive straight into a deep pond. Because of the snorkel it ran for about two minutes....then the water leaked into the distributor and into the engine & transmission and it stalled. Oh, and the water was up to the driver's chest while he was behind the wheel. (there was even water in the gauges ) So a snorkel and moving the vent lines to the snorkel won't keep you from stalling in the middle of a puddle/pond/lake/river but it will help.

ThunderbirdJunkie can you turn your snorkel to face backwards? I've seen a couple of people do that so they don't splash water into it.

 

[ThunderbirdJunkie]

Yes.
Snorkels are not for playing submarine. They are to prevent water from getting into the intake.
They prevent you from hydrolocking the engine. That is their only purpose.
