Mike,
Yes, the new crystals will improve the filtering in the K2 - there may
be a few exceptions, but that is not the rule.
The filter response will be smoother.
Your K2 RF Board also likely has the older crystals, so change them as
well. Get the matched set of 14 crystals.

I have an early K2 that has the original type crystals in both the CW and
SSB IF filters (marked with ECS 4.91-20). If I am not going to increase the
bandwidth of the SSB filter, is there any reason to replace the old
crystals with the new units from Elecraft? Will the new crystals improve
performance?
Thanks for any feedback.
