Next time try this technique.I always grease the seal, never over tighten & stil it’s always a complete **** to undo. With terrible access & only room for less than an eighth of a turn on a wrench I’ve found the three legged tool the least worst - considerably improved by wrapping the legs in thick elastic bands to reduce slipping.
I now find I only have to butcher the thing with a screwdriver about every third year?
Grease the ring.
Fit the filter with your non dominant hand, tight.
Back it off with your dominant hand by a tiny amount, just enough to take the torque out of the ring.
When you come to remove it with your dominant hand you will have no problem.
Folk overtighten canister filters, they don't need to be massively tight to seal. They only leak if the seating is dirty or the ring distorted ---------- BY OVER TIGHTENING ! ---------- and not greasing!
