As per post in regards to the Code 16 I am getting on a 90 Civic DX, I have decided I am going to go about getting the injectors replaced on the car, so my question is, what is the difference between Honda branded injectors vs the ones you can buy from the online part stores ect? Does anyone have any insight on these, btw Honda wanted 180.00 per injector and that seems a little high, but do I get what I pay for? A friend mentioned that the Honda ones were build with a higher quality ceramic..is this true?
