In my old/new 200 nozzles? I think they're the same, 300 looked a smidge bigger but they're smaller than a hair so hard to tell..
After putting a few miles on these DTP nozzles I'd be happy to recommend, 15 quid+vat at Derwen Diesels. The old bosch weren't terrible to be fair, 150k+ miles on mostly African fuel so hats off, pretty good going. if the fairies had swapped nozzles overnight I wouldn't really notice, but the new ones run with less smoke under load and I've been able to turn the fuel up to where it used to be without chugging smoke out. Could really do with a good run to see
