i recently upgraded to 720cc injectors from 550s and im wondering if i got the right ones because they look way small. They look like stock ones and are far smaller than the 550s. They also have the pin sticking out the end instead of the large opening of the 550s. The part # is PKCX-720. The flow chart that was included shows 720s but im jsut making sure. They dont have the RC sticker around them either which all the other sets i got from the did. They do plug in and everything correctly. Do i have the right ones?

 

awhile ago rc switched their larger injectors from lucas to bosch. they do in fact look different. do your injectors have a blue cap on the side with the pin? don't worry rc has their stuff together, i doubt they would mess up.
