ok i got a kit from here and when i got it there was this bolt stripped onto the back of the nozzle and on the very tip there was threads on it (from top to where it says shark nozzle)

is this normal?

thats a pic of it plus like where the nitrous actually sprays some of the sides have been broken off will this effect performance?

 

wow.. from looking at that it looks like he improperly installed the shark nozzle... it was supposed to thread into a plastic nut if i remember properly
