What Jon said....x 2. Regarding the pan gasket, most reputable filters
come with a cork gasket. While those will seal ok if you don't over
tighten the bolts, you will always have to clean off the old material before
installing a new gasket the next time. PITA!

Better, much better, is to get a reusable Mopar pan gasket from your
friendly dealer's parts counter. They are multilayer metal/rubber. I've
reused mine at least a dozen times. It does not leak and your only cleanup
is wiping it off. A little pricey but well worth it in effort and time
saved.
