Can someone give me some info on fuel injectors. The way I see it, they are not much of a ware item, and should last the life of the car. But I still see them used on eBay for less than 1/4 of the original price from FMS. I want to upgrade from 19s to 30s, but I haven't even started and am over budjet. I need to buy some stuff used and thought this would be a good place to start. Any insight would be appreciated.
