This should be perfect for the long term.

10/10 recommend the upgrade. Took about 30 minutes, need to jack up the rear left and right a bit for access. Piece of cake.

did you experience any error codes appearing?

No, (I assume you mean CEL) and I am not aware of this even being a thing, honestly. But if I do experience a CEL I'll definitely come back here and report it.
