i ripped the top o rings off my newly cleaned injectors and was wondering if i could buy them @ local auto parts store pretty sure there the same sizes(850 & 550) or would i need to purchase from injecter specialty store..

 

They prob are special treated to withstand heat. I would try your local mazda store. OEM

 

Are these Denso injectors (or extremely similar) just like stock? just ask for OEM style o-rings for a 2nd gen Rx-7 at any part store, they will work. If you have Bosch injectors by chance (not likely unless you have 1600's) get o-rings for a recent model Ford F-150.

You say 850 and 550. I didn't even know people ran 850 top feed injectors much.

 

they are 11mm o-rings

 

got a good deal on them so couldnt turn them down..550 primary 850 secondaries all cleaned..anyway i got them thanks all..
