As an example to you all..........
I run a CITROEN coil pack on my car from a BX 1.4 litre.
(Found this coil on sale in halfords in a bargain bin for £5)
I run 1.0 millimeter plug gaps and peak 36 psi. Had the same set of plugs in the
car for over 1 year without ANY signs of missfires. !!!!
PLUGS: BCP7RES
LEADS: Using original ford/beru leads modified to suit coil pack.
