This is the most recent thread about cone air filters, so I guess I'll ask this here:

In all the writeups I've seen so far for cone air filters, they all use some kind of apparatus, (Rusty's or homemade) that reattach the crankcase breather to the intake hose so that the air for the crankcase is still coming through that one main air filter. Of course this requires a special tube with a nub for the crankcase breather tube and doesn't allow you to just run a straight tube clamped between the cone and the flex tube. What I'm wondering is, would it not be possible to just stick on a seperate crankcase filter, like this:



And then just use a straight piece of PVC or some crap to attach the cone to the flex tube?
It seems to me that by retaining the stock crankcase breather setup, you're overcomplicating things.

....I later took a stock air box and modified it for a higher intake tube and put the cone filter inside to protect it

I heard the same thing from a performance shop. I just goto Napa and get the replacement filter that's made by WIX. When it gets muddy/dirty from off-roadin' I just throw it away and by another...

I use to be a huge fan of K&N until I did some research on them. They do let more air in. Larger opening in the filter material allows more air in, more clean air, more dirty air, more water if you get in that situation. The LAST thing a Jeep needs is more chance of sand, dirt, and water to get into the engine. It is not a street car, it's an off-road vehicle. Off-road vehicles require different things then a street car does.

After talking to the airbox and air filter engineers at work, I am now a little more informed then I use to be. I know that a stock factory air filter is the only way to go. It is more then adiquate for your rigs. If you want to be a bit safer in water, and get a little more performance use a snorkle set up with a sealed box, and a factory type of air filter.

Did mount the box at a higher loaction? Or just 'relocate' the hole in the box.

That makes sense, since my vehicle is more of a pavement warrior, I figured their wouldn't be too much harm in getting a cone filter. And also for protection I wanted to fit it still in the stock air filter box, of course with a tad modification. I've had the jeep in water once, and I wish for that to be the last time (wasn't deep at all, but the stock bald street tires scared me w/ lack of traction). Since I plan on getting some better exhaust I wanted to upgrade the air intake as well for overall better performance no matter how-small it may be. Somethin's always better then nothin!

On our mowers, Walker MFG, the air cleaner has a little snorkle type thing that sticks up and over the mower body/collection system. Inside the top of the "snorkle" is a little suction driven fan that spins the air flow down the tube and into the filter and then into the motor. It looked pretty efficient to me. Im going to have to try that on my XJ. (I was looking into the cowl induction like on MadXJ's site)
