I would rather run an old sock than Spectre filters. The systems I have seen were always rather cheaply made as well. What are you hoping to gain from it?

All indications and readings I've gone over found that an AC Delco paper filter is the BEST filter to buy for a Jeep. That being said, I put a Spectre in mine before I knew all this, as they are just as good as an over priced K&N. THAT being said, the stock airbox allows more than enough airflow for these motors, so you will see ZERO gains with any kind of aftermarket airbox UNLESS you upgrade the exhaust...and everything between. The engine bay design holds a ton of heat, louvers on certain spots on the hood will allow cooler air around the motor, cooler runs better. You could run a short snorkel if you wanted a true 'cold' air intake with an ice can (for you sport car folks out there). Save your money for a brake set up or better yet, Poison Spyder Hood Louver.

I would suggest saving you money too. The Hood Louvers would help you way more than the CAI would and they look better too. Your not going to be driving arould with your hood up or off.

I am currently using this setup and I love it. I didn't get it for more HP or MPGs I did it to get the intake above the hood level with out getting a snorkel. Only thing make sure your cowl is draining properly other wise you'll suck up water. Learned that the hard way.

I thought the same thing until I checked the tube to the throttle body and saw how much dirt it let through. You should go pull yours off and take a look and you will think twice about putting it back on.

Installing a K&N air filter is probably one of the worst things you can do to your engine if you ever wheel in dirty/dusty conditions. K&N air filters keep the dirt & dust out about as well as a screen door keeps the dust out during a Texas dust strorm.

There was a thorough lab test of various air filters several years ago & the K&N came in dead last in its filtration abilitity. Not to mention the TJ's air intake system was specifically designed to easily be able to flow more air than the engine can consume at wide-open throttle & redline RPMs so installing a filter for more air flow literally does nothing.

Here's just one chart from that air filter test, the words below that chart are copied verbatum from the lab test. In other words, their words, not mine...



"In the chart above it’s important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction. In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms. Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt." (end of quote)

I removed my K&N air filter after a friend showed me how much dirt & grime was getting past it. The inside my air intake system downstream of my K&N was beyond grimy.

Somethings not right then. Are you talking about the full intake system or just the filter? I'm using a Spectre filter with stock air box and nothing changed. Either the filter isn't seated right, or the top isn't seated on the bottom case properly. Mine didn't make any changes at all. And I mean ANY, not sound, mileage, codes, power, etc, etc. But I knew this before purchasing it. I buy them thinking long term, as I typically own my cars 15+ years, until the body and frame rot. And as suggested previously, you can run a pre-filter on K&N or Spectre either the bag or foam type. Tho none were tested. I know when I was in the desert, a lot of folks swore by them. But I myself have no experience with them.

he bought the full intake systems, i wasn't impress by it. when you drive the jeep you can hear the suction of the intake through the a/c vents on top of the dash.

I love my spectre CAI system. Did not gain any noticeable performance & MPGs

advantage1 : more space in engine bay (you can install compressor, storage-box...)
advantage2 : cool looking.

disadvantage1 : Breath noise
disadvantage2 : $149.00

Note1 : make some water shield on the plastic intake duct in the cowl.
Note2 : make sure that cowl drain is clean.

Gotcha, missed that, lol. Thanks. Again, with the dust issue or even water/mud issue, heres some pre filter wraps:

K&N Air Filter Wraps

AirAid

Yes, it goes over a specific filter, but you can just zip tie it to the outside of the stock air box if you are worried. Its all about options in the end

It sounds different & you can hear a sucking sound with air intakes like that but it's not providing the engine any more air than the OE air intake does.

You can buy a cowl cover that helps a lot and the sucking sound doesn't sound that bad you can always throw a little dynamite in it should help a bit.
