Yes. That's why I dug up a list of compatible filters...look a few posts above this.bchulett said:Does that spin on the same threads and OEM mount ?
I may go this route next time.
Actually, mine is mounted horizontally to the rear, and clears just fine. I have to disconnect the oil pressure sender but once the filter is out I just tip it up and pull it out through the gap above the filter. The large filter is the same diameter as the OEM one, so there's not a clearance problem there.Wiley Coyote said:My ’91 is a Canadian model and may be slightly different than yours. My oil filter is on the passenger side and points straight up, but has the SAE threads. If yours points down (i.e. you have to unscrew it from underneath the Jeep) or is mounted horizontally the oversized filter may not fit (it’ll be pretty tight with out hitting the starter).

When you ask the guy at the counter for an oversized filter for your Cherokee its probably going to confuse him, so just ask for a filter for a 80s Ford F150 with a 5.0L (it’ll have K&N H-3001 and all of the other filters listed as well).

PapaPump said:my jeep is a '92 and has the 3/4 x 16 threads. there is a big warning sticker in the engine bay "caution: new oil filter size use pn 5281090 or eqivalent." that makes me think the new filter started in my year. not sure if that is 16mms or 16 threads per inch but i think it is the latter and my jeep uses sae threads.
old_man said:You guys missed the best filter out there. The Frantz toilet paper oil filter. Costs me 18 cents an oil change and I will put its filtering capability up against any other filter.
This is not a joke.
