Not sure if this is tech or chat...
I was doing some PM on the '97 FZJ80 today. While waiting for the AT fluid to drain out I decided to put in my new OEM Air Filter (thanks CDan) and take out whatever the PO had in there.
BTW, I know most folks say to remove the air cleaner hose so you don't crack it but I've found that by simply loosening the clamp at the throttle body you can rotate the hose and the air cleaner cap enough to easily remove the air filter without putting stress on the hose.
Anyway, when I pulled the filter out I noticed a fair amount of oily grime on both the top and the bottom of the air filter and in the bottom of the can. I recognized the look of the filter as that of a K&N and sure enough, when I wiped away the grime from the top of the air filter it was clearly marked K&N. The other thing I noticed was that the size of the K&N air filter was considerably smaller than the OEM air filter.
I've read various threads on MUD regarding K&N air filters and about not using them due to the oil in the filter getting into the hose, MAF, etc. Based on what I saw I would have to agree 100% with those that warn against using a K&N (ran one for years on my '99 Durango thinking it was the best air filter out there ).
Here are some pictures showing the obvious size difference between the filters and of the grime that I wiped off the air filter and out of the air filter can. The shop wipe with the oil on it is the one I used to wipe off the filter. The other two were used to clean out the air filter can. I used BOTH sides of the shop wipes and the other side looked about the same as what you see grime wise
P.S. Anyone want a K&N air filter before I toss it? FREE but let me know quick
