Differences between injectors with index 12

Irbis · 01-29-2023, 01:37 PM

Hi, I have bought 2 injectors with index 12 - the part number: 1353 7585261-12.

I have noticed that there are differences in other numbers

- on the metallic material: E0 vs C0
- next to the QR code: 593201 vs 580237, 140926 vs 170316

What those numbers mean ?

Moreover one metallic ring looks different.

I guess that those injectors may have different production year. It is possible to identify the production year based on the above numbers ?

593 201 vs 580 237 are the measured flow characteristics of that particular injector. These values need to be programmed into the DME when you install the injectors. These will be unique to each injector. That's all I know.

That metallic ring is an injector decoupler ring. They all need to have those...if they are missing, you will need to buy some more.

Also....make sure you replace all of the tip seals on the injectors with new ones before you install them.
