Been awhile, but if my memory serves me correctly, the D90 filter boxes were round/tubeular. The square Disco box is causing me to loose a couple inches of funtional wheel travel as it petrudes into the wheel well. Perhaps one of you stock D90 owners could be so kind as to provide me the dimensions of the filter box???? I am looking to swap square for round so unless someone tells me otherwise, I WILL BE IN THE MARKET FOR A D90 FILTER BOX$$$ HINT HINT I was also curious as to if this would affect the MAS (mass air flow sensor)? Thanx again for all of your time.

The '93 NAS 110, and '94 & '95 NAS 90 used the round filter housing, which is mouted to the bulkhead, horizontally, behind the plenum. The MAF is hard fitted to the filter housing, with a rigid fiber tube running between the throttle body and MAF.
The filter used on Classics is much the same, it just mounts in a different location, and may be better suited to installing in your Disco oriented engine bay.
The '97 NAS90 uses the quare, plastic filter housing much the same as the the Gems Disco.
You could probably adapt a filter housing used on the earlier (LUCAS) engines, Rangie or Defender, but the manner in which the MAF connects and clamps to it will need to be modified. You wont be able to use the earlier style MAF sensor.
I am not aware of any official warning against using the K&N filter. It's just a highly debated item as to it's usefulness. K&N's claim is that they allow more air to pass through, and under normal driving circumstances, that may be true, but I know from experience that they will plug up severely when driving in very dusty enviroments such as dry dirt roads. Much of the offroading I've done has been up in the Allegash, of northern Maine. These roads are unpaved, and almost all are on paper company land. The logging trucks haul the mail and stir up clouds of dust. If you pass one going the opposite direction, you'll be in a cloud of dust for nearly a mile afterwards and every square inch of your truck will be coated, inside and out. When you see one coming at you, you have to roll the windows up and close the vents ASAP. One day of that and your filter will be so choked up the truck may not restart. The oil coated filter will not let any air pass through.
I ended up cleaning my MAS (DID NOT USE BRAKE CLEANER) and havent had any isues since. On another post I was ridiculed for this. Bosch MAS'S that sensative to a lil spring cleaning? I live in a dusty farm community and I think my snorkel does a good job of shoving dust up my K&NS rear, gumming up my MAS.

It isn't just the D2. All hotwire MAF sensors get messy if you over oil the K&N filter.
x2. A friend of mine had to replace the MAF on his Ford Ranger after installing a K&N. Buyer beware!

Of course K&N will argue this, but hot wire AFM's and oil permeated filter media just do not mix. They will kill the Air Flow Meter. Not a matter of if, but when.
This is true of any make and model. The main problem is over oiling after cleaning, and it is very hard not to do. But even with the "proper" amount of oil, the accumulation will ultimately reduce efficiency by increasing resistance, and finally killing the piece. I experienced this on more than one occasion, even getting in a pissing match with K&N over a customers AFM. I'll never use them again.
