I say if the gap is larger than stock specs, get a higher output coil because widening the gap is going to increase the coil's dwell time (saturation,) which in turn will make it output at a higher voltage and possibly reducing it's life from operating at a slightly warmer temp.
Then again, having a coil with too high of an output will only eat up sparkplugs like PEZ under low compression ratios (8.8-9BAR)
Higher CR=higher voltage needed to overcome compression
Lower CR=lower voltage needed to overcome compression
You don't have to know everything, if you know where to find it.
When you do ask questions, you may look ignorant.
When you do NOT ask questions, you will STAY ignorant.
