Hi Folks, any idea why Jeep wants the KJ 3.7l plugs changed at 30k? My OTHER car recommends 100k!

Given the slight degree of difiiculty in replacing the spark plugs, I'd recommend platinums at the next replacement interval....I used some Bosch Platinum's in my wife's '02 Jeep Liberty Sport 4x4 w/3.7L. Spark plugs are a thing of the past for me now, however.....the '05 is spark plug-free.

Did you say that the Jeep Liberty 2005 doesn't have spark plugs ("the '05 is spark plug-free")? Otherwise, its just my misunderstanding. Thanks ...
