Mud on the top of your engine, and you install an open filter intake. Hydrolock waiting to happen.
I have a Cai and haven't hydrolocked. Don't judge them until you have one. It's better at keeping water out than my stock airbox
sent from my EVO 3D
i havent mudded in a while, and its mostly from cleaning it the last time with the pressure washer, that just sprayed everything everywhere!
i will be trying to make something to try to keep water and mud away... just have to think on what would work
...the original air box... :shrug:
I have alot of faith in the stock airbox. I submerged my entire engine bay up over the hood and got out ok. The box was full of mud and water, but nothing got into the engine. I know with an open filter it would have been like sucking up water with a shotvac. CAIs scare me on Jeeps.
i am pretty scared.....
my last question would be is there any other way to get performance with the stock airbox?
wouldn't a drop in k&n do the same as a fram, or other ordinary drop in?
I JUST bought and installed a K&N drop in filter. So far, it's great! I've noticed a slight gain of power and mid range punch. Haven't had it long enough to know any difference in fuel economy, but from what I've heard, you can expect 2mpg's. I wouldn't waste $300+ on a K&N CAI anyway since it only adds on about 6 hp. The drop-in is $50 and still has the "million mile limited warrenty."
I also put in new platnium spark plugs which should also help with the milage.
ive seen people use a 5 liter keg as a shield for cone filters...just giving an idea
i have a kn drop on filter no mileage gain its just better filtration than a plain paper filter but i do like it alot better than paper filters, wouldnt call a kn intake tube a complete waste but the kjs stock intake tube isnt very restrictive, the fipk is ment for a vehicle with a pos stock air intake
Of every vehicle I've own, which includes many performance vehicles, I have only seen a use for a CAI in 1 of them. The only reason I liked the intake on that was because it was supercharged and needed a bigger filter to run more boost. My 12 second mustang needed no cai, my mid 13 second gti worked perfectly fine with the stock air box, I surely didn't want a cai on my wrangler. I think intakes are a waste of money on naturally aspirated cars, and even on most fi cars.
I think there's a recall on the FIPK filters too. (dunno)
After running quite a few different setups on mine best so far has been a Amsoil filter in the stock box with a 3 to 4 inch hose to the grill area. You can have all of the K&Ns you can load up, they're not that good unless you are running a full on race motor or something
All that CAIs do is suck in a ton of hot air
There is a way to actually get cold air into a CAI and NOT get water in it... mount it on your roof with an umbrella ove the top of it! (lol)
The stock airbox in the KJ is actually very well designed. It's not as sexy as the open intakes, but you'd have to work extremely hard to take in water with that stock airbox.
COLD air intake.
Sucking WARM air from right NEXT to the engine.
Stock airbox sucks air from outside of the engine compartment.
Air outside of the engine compartment is way, way cooler than inside.
Also, you have lowered the intake height, which will make it more susceptible to water intake.
So which one is cold? Which protects more?
also its been said before. K&N filters allow better airflow because they have bigger holes. bigger particles can flow through bigger holes. What does that mean. More dirt being ingested by your engine.
When I was younger and dumber I tried a hot air intake and I immediately noticed my oil was dirtier than it used to be. This was in a F150 super crew though. Sounded like it was going to suck in the hood! oh and zero performance gain and about 1/2 to 1 mpg gain. Probably because of the hot air being sucked in during the cooler seasons. Mine was chrome like the one in this thread. Feel that sucker after you've driven it a little while. I bet you'll be lucky to be able to hold your hand on it.
You know, it was different back in the day when the air intake was right over the engine. Then a "Cold Air Intake" actually made sense. Now (and a lot longer than a while back...), intakes bring in cool air from somewhere outside, usually, making cold air intakes.... not cold air intakes.
