Replacing the injectors on the NG900s and 9-3s is pretty well unheard of. What's the problem?
You can get massive power increases with this engine with the stock injectors, so no need there.
Use a good fuel system cleaner, in the US, Techron Concentrate is widely available and works very well. Use 2 times per year or ever 8K miles. The RFG-II gasolines, especially the low volitility summer grade fuels create deposits, even with premium grade fuels. The result is hard starting with the first cooler temperatures in the fall.
Do be clean when installing the new filter. We have a pattern of fuel pressure regulators going bad right after filter changes. You need 4 new sealing washers for the filter. Work in a well vented area, preference for out-of-doors! The fuel fitlers seem to be good for well over 100000 miles.
