The filter Quad Seal Gasket for the Challenger Oil Filter.
Refer to Owners Manual
Bought my oil filter in May of 2019 and it has not leaked a drop. Removal of the filter can aloso be done without spilling a drop. Great design!
The seal is too thin. I had problems with it leaking. I tried just hand tight, it leaked. Then three more tightening settings and it still leaked. Tried a new seal same thing.
The seal is way too thin! You cant tighten it enough to stop leaking. We tried 3 more quad seals, all with the same result... unacceptable seal failure. Wonder if they recently changed manufacturer of the quad seals... ?
