Well you pulled this part out of context and there is a bit more coupled with it.Thank you everyone for the input, especially GIACUser for taking the time to get into the technical details.
One last question- assuming that there are no misfires occurring, is there any reason to not run the larger gap? My understanding, as was mentioned above, is that a larger gap will result in a more efficient burn. Are there any ill effects outside of misfires that I should keep an eye out for? I plan to log periodically just to keep an eye on things as I put some miles on the plugs and coils.
The R8 coils (06E905115G) are paired with 8 range plugs in boosted OEM applications (3.0SC). These are the plugs that have worked best for my APR K04 tune (PFR8S8EG) gapped to about .025. I still get slight misses near red line but better than several different coil/plug combinations I tested.I am shocked at the number of posts in multiple forums by people that are saying the 5.3 ohm R8 coils have a hotter spark than the 3.3 ohm coils. It is simply not true. More voltage is released to the plug with a lower resistance coil and requires a larger gap for better performance regarding ignition. The R8 coils are good when there is increased boost and resultant combustion that may disturb the arc of the oem coils. Then when a tighter gap is needed, is when the R8 coil may help because it works better with a tight plug gap. You can actually switch to a warmer plug with R8 coils due to the reduction of heat from its arc. The R8 typically uses a 6-heat plug because of this.
