Yes, also when you have your filter off, throw some sand/dirt in the intake. This way you can see what running a low quality filter would do to your engine over years of use! (just kidding)

Horse power won't give a noticeable "seat of the pants" feel until about a 30 hp increase.

I've tried K&N filters before, on cars that made a LOT more HP than a Jeep in any kind of stock flavor, and never once noticed a difference in performance from an open element paper filter. The only thing I noticed was a lighter wallet.

I'll keep my money thanks.

I replaced the air intake tube on my '97 with a steel tube from Turbo City. I only did so to gain the CARB (Calif. Air Resources Board) sticker I needed for my TJ to pass the visual smog check. No (zero!) difference in performance despite all the hype from Turbo City... not that I was actually expecting or even hoping for any.

I had to replace the modified OE air intake tube with a CARB compliant replacement because I had cut the OE tube off to install a York compressor that intruded into the OE air filter box's space. The Turbo City tube was the same length as the OE I had cut off but its benefit was it had the CARB sticker I needed.
When you have a choice, buy American.

Why are you trying to replace it? , perhaps if you explained why you need to replace it, someone could point you in the right direction. IE where to locate a stock replacement tube.

Or is there no reason to replace it and you just want to do it for looks? I know its not the louder sound you are after, because you want to keep the stock air box and just replace the piping from that to the throttle body, which wont make the intake any louder.

I would think that the options are limited, Stock, aftermarket CAI/ replacement tube, or home made.

As for home made, I have seen PVC piping used and Exhaust piping used to back yard engineer intake tube's. I wouldn't use either, but if i had to pick i would use exhaust piping.
