The plate is just 4 bolts, so it's not much trouble to remove and it will give you easier access for your first go- round. You have options for the tool as well. Like I said , I use a band wrench, others have mentioned the cup style adapter that will work fine too. Only thing I don't like about the gripper style is you have to be careful to not deform the new filter when installing. I have all 3 in the tool box, so it comes down to what works best for you.
Just be patient, wear latex gloves, and If you are prepared to make a mess you won't be disappointed. Do not wear your favorite shirt.
The next time will be way easier!
