HI Steve, High voltages cause an electro-chemical breakdown of silicone Si-O bonds. this breakdown is making the boot thinner in that area and eventually the HV electricity finds a path to ground with less resistance than a sparkplug gapped at 0.010".

Best way to find spark leaks is by turning off all the lights in your shop and watch it in the dark while idling. Bad wires and/or boots put on quite the light show.

The smile on her face when she got out of Katlan's car was so great. Even better after doing the drifting. That says it all. Loved the video.

Looks like the pin hole started right at the seam of the boot

:_dewey:Nice to see the whole family. For Kyle I think drifting improves driving skills for the unexpected slide on the drag strip. Those high power ignitions are causing Corona inside the spark plug boot. This happens when you hit the Corona Inception Voltage (CIV). Corona produces Ozone in the air voids inside the plug boot. Ozone decomposes the rubber/polimer boot material until it blows a hole through it, from the inside. fill your boot with delectric grease and then shove the sparkplug wire in the boot. The grease is meant to fill the air voids. :_dewey:
