I'd like to get $125 a set. the Delphi's have some warpage to the tip, but did function fine in the last car they were in.
The 680's appear to be in good shape with a little goo/dirtyness near the nozzles but functioned fine in the last car they were in.
Neither have good seals on them.
Stock 450cc $60 shipped.
750cc showing the tip warpage
