Fuel Injectors VW Golf IV AHF

Hi,

Can someone please provide me with the part numbers for the fuel injectors of a 1998 Volkswagen Golf IV AHF?
I've had larger nozzles installed since I bought it, and now I want to replace them.
I have the following information:

3 x Nozzles 028 130 201 G.

1 x Nozzle with needle lift injector 028 130 201 J.


Can someone confirm this for me? What should I look out for when buying new nozzles?
I'd like to buy a used one if possible. Would it be okay if it has been refurbished and inspected? My Golf already has almost 200,000 kilometers on it, so I don't necessarily want to buy a new one from the dealership.

Thank you very much in advance.

You don't need to replace the entire injectors. It is sufficient to replace just the injector nozzles. These are the only wear items and also the only difference between different engine types or tuned vs. non-tuned engines.

"Personally, I wouldn't buy used injectors because they are usually only replaced when they have very high mileage and a correspondingly poor spray pattern, or when someone is trying to sell them on eBay. To overhaul such injectors, the injector nozzle needs to be replaced, and the opening pressure needs to be readjusted."

You can find the injector nozzles, including the adjustment settings, here at the Dieselschrauber shop (shop.dieselschrauber.de).
