Yup, use NOTHING. Just insure the threads are clean and torque per specs on the filter kit instructions.
Be sure to use ONLY the gaskets/O rings what replace what you have in there now. Said another way, the kit will contain more gaskets/O rings than you will use, as the kits fit a number of different applications.
