My local dealer wants $60 for the whole oil filter assembly. They claim that's all that's available from Chrysler. The next closest dealer is a Mercedes dealer 45 miles away. They have the filters for $18.50, but want $1.16 for a gasket. Is there a different gasket besides the 4 o-rings, or are they just selling them separately? The only reference to gaskets I see on the forum is for the o-rings. Just wanted to know what to expect before driving down there this weekend.
