B58 coil pack on N20

Hi Gents,
Wondering if there's any real benefits in using these coil packs.
In the US it seems to be a popular mod for those with remap ecu.
Yes Im aware that some mods would need to be done to install these.

I'd imagine a complete waste of time and money..the N20 coil /spark system was a much revised version of those before..if you have an earlier N20 much better to get the TU HPFP that came later!

High pressure fuel pump..an uprated one was fitted from 3/2014..

If you’re remapping a N20 the later pump gives more headroom to avoid inadvertently running weak..
