I just got my RC550 was in the middle of putting them on. I notice that the mouth/head of the injector is much bigger then stock. i'll have to force the o-rings onto the injectors but it's way to big to fit into my intake manifold. if i try to not use the o-rings it wont even sit properly on like a stock one. how are these injectors suppose to sit?

 

i install my rc 550cc on a d16 and it didn't fit well either. i used their rings they gave me and my stock spacers. fit perfectly. good luck.

 

did you have to trim any parts of the o-ring

i just trimmed my stock rings to fit the bigger injectors
