View Full Version : Injector failed :/

10-13-2012, 10:04 PM
I need to replace my injectors I did a quick fix and just changed one of four but it was a auto zone injector 45$ so there's one that doesn't match the rest I don't like that

I looked around online and found some injectors ranging from 100$ to 200$ any suggestions as to which would be a good buy?

Oo and seeing the difference in cc, I'm not sure what the means but theres higher ones and lower ones how much of difference is it? Or does it depend on how you have the engine modified

my knowledge is very limited, so take this with a grain of salt until someone comes along with a more reliable answer, but from what i do know, this is what i THINK you should do. just try to keep it to OEM specs. "cc" usually stands for "cubic centimeters", which is a measurement of volume, and in this case, the amount of fuel that it injects into the cylinder. getting larger injectors is usually only recommended when you boost an engine. can anyone clarify this? lol

do you know why your injector failed though?

I suggest getting a set of stock injectors that have been professionally cleaned and matched or send your three current ones out for service (and getting a fourth that matches the other three).

You haven't indicated why you think you need to replace your injectors and there's a whole lot more involved in using injectors of different/higher CCs. You can't just replace the stock injectors with 750cc and expect a sudden boost in power.

Send the OEMs to a cleaning service. Most have a one day turnaround, so depending on the shipping you pay for bothways, you will have them back quickly. They will include cleaning, before and after flowtesting, usually new pintle caps and screens, pattern testing, and a printout of each injector's performance. Most services will get them matched within 2-3% of each other.

Since you are west coast-based, I would suggest:
RC Engineering


Those on the east coast, I suggest:


There are others, but those are the three I have used and was very happy with the results.
