I think to answer the original question as well - the N53/N54 HPFP were available to order on two part numbers. One was the actual part number and one was the warranty party number. Both parts were exactly the same and would arrive in the same box with the actual part number on the box but the warranty part was half the cost of the non warranty part. This warranty part is no longer continued. I think I got one of the last HPFP available on the warranty part number in Europe a year or so ago.

I think the same thing applied with the injectors for the N54. There is or at least was two part numbers which were the same part, however one was significantly cheaper than the other. Might still be available in the US.

Shame it never extended to cover the N53 injectors though.

Yeah pretty sure the n54, n53 and earlier n55 were exactly the same HPFP. Interesting about the warranty pricing!

Anyone else confirmed by testing that N54 injectors work on N53? I remember reading on bimmerprof, that N54 index 12 (N53 stops at index 11) had different spray pattern for pollution management.

Don't know for sure, but I've read on forums that the N54 injectors overfuel if used on the N53 engine. They're designed for much more fuel-hungry turbo motors like the N54.

Hi. What is fuel consumption after update? Thanks.

The consumption is about 7L/100km in 80-120km/h cruise, 11.5L/100km 28km average speed in city area. The flow rate is relatively high. I tuned my n53b30 to 296ps 350nm with stratified charge. No EGR DPF delete.

Others have recently reported non problematic mixing of index-12's with other index #'s even within the same bank! I've non problematically replaced used injectors with used injectors without replacing couplers or teflon seals on N54.

I will consider this exchange as well. Local stealership wants a fortune to replace 6 of ...9048. Thanks

thats nice,but i think n53 grey injectors can't be mixed with n54 black injectors in the same bank. the injectors in bank1 and bank2 should be same color.

Your original query is from 2017. Still contemplating which injector to go with?

No, in fact i'd forgotten that i'd opened the original thread. It was more out of interest actually, the comparison of n53/54 injectors. But my n53 has been happily (touch wood!) running index 11 n53 injectors since around 2016 though I guess i'm probably on borrowed time especially as i do mostly very short trips.

Requiring individual coding they're either going to work in a cylinder or they're not, regardless of bank placement.
