Has anyone tried any performance coil packs on the 5.4s? I have a 3v and am considering something like:

rest of the list is:

do these seem compatible? and what will improve performance (ie lower impedance or high voltage etc)

cheers

Those coils will work but I wish I could find an article I saw recently where they fitted coils from ?(can't remember the brand)on a 3V 4.6 and they picked up an amazing 27hp!?! f**k incredible!
They couldn't believe it either so they switched back to stock two more times to confirm it!
I'll see if I can find it.
