I'm trying to find the correct part number for the Bosch injectors to fit a mk4 R32. It's a bit confusing as there's a lot of conflicting info on the internet.

I've narrowed it down to two parts numbers 0280158123 and 0280158117

The number ending in 123 has the extended nozzle like the OEM injector, but on the Bosch's catalog it shows this as being a 'compact' type which means the injector body is shorter than OEM. This wouldn't fit correctly. Then again suppliers of this part number list it as being the correct body length.

The number ending in 117 doesn't have the extended nozzle. But most suppliers of this part number list this as the one which fits the r32.

Does anyone have first hand experience and know what part number you have fitted? And would anyone know where to get the correct injector but with a larger CC than 550.. I need to be at least 630cc @3bar.

Any help would be appriciated!!

0280158117 Is the 550cc injector that fits R32 engine, and the one most people use.
0280158298 is 650cc injector which also fits R32 engine. I've had both in mine.
I also had the Siemens Deka 630. They also fit but requires a 10mm spacer to lift the fuel rail.
