I don't know if that is a good idea,i think injectors are flowed a little different.Meaning nismo and rc engineering could flow a little different than each other.If you know the brand you have use the same injector.You can also pull that injector and take it to a injector place and they rebuild or clean as necessary.Good luck.

It is very important, especially on a FI car that you have a good, balanced set of injectors. I've seen injectors from the same manufacturer vary by as much as 10%.

Could you get away with just replacing one injector blindly? Sure, you could get lucky and get one off the shelf and out of the box within balance of your set. Or, you could get one that is way over or way under and your performance and fuel economy will suffer.

Another option would be to send your set in for service. We could perform our Dynamic service and clean all of the injectors, install new seals and filters, and flow test them, report included. If we find one is bad or not repairable, we could let you know and go from there.
