Unless you've got a closed gap or can see a significant difference between all 4 then leave well alone and fit them.

If you manage to do that I will be very grateful!
Thank you in advance...
Well I ran a back to back test. It gained and lost an HP or two here and there, but for the most part all the runs were line for line.

TBH it's not a shock, the stock ignition system is more then enough to handle the boost levels these engines see. Even in higher HP application colder plugs and tighter gaps will be more then enough.

Thank you very much for your valuable feedback.
It seems that keeping the stock ignition coils is a wise thing to do.
Unless they fail for a reason...
