What vehicle are they to go in? Most vehicles like OE plugs and by the acronym it sounds like this E3 is using 3 ground electrodes but I swear only one can take spark at a time not all three or some with two and four I've seen.

No matter what you do the spark will seek the easiest ground for itself no matter what you do. If two of three electrodes don't get the jump of spark then others are just in the way IMO,
