Hi Guys,
I always thought the ignition system on the n54 was kind of weak (easy to misfire). I have been running ngk 5992s and they still wear our pretty quick (start to misfire) with no visible explanation of failure.
In looking for a solution I was thinking the mini coils may be an option since they use the same connector and work with the larger gapped ngk 5992 out of the box. After researching more it looks like all of the newer motors use larger gaps even with the same coils we use. The n63 uses a 1.1mm gap on a single electrode for instance. I am kind of thinking that the 0.022" tapping may be too small and that 0.031-0.035" is more realistic for a single electrode setup.
Any thoughts? Were people misfiring on NGKs at the stock gap? I generally agree that a smaller gap is good for more boost, but the switch from 3 electrodes to 1 changes things a bit I would think.
Thanks
