Are the fuel rails in the 944 N/A and 951 the same? What about the injectors? How long do you think our injectors can last? Mine have 144k mile on them and I was wondering if sending them out for cleaning is worth it.

TIA

 

The later rails are all the same, the ones with the FPR and FPD on opposite ends. The injectors are different. Not too sure on the life of them.
