Ran across these today... Never heard of them before. Newbie owner here in MI just bought an MS3 off a local lot and had these on the car already, posted a pic when asking about mods already installed. Only source I could find for them is an eBay link, no other original website or such. @AYOUSTIN and I seemed a little curious as neither of us hearing of them before. Is it another gimmicky proclaimed eBay "performance" mod? Quite possibly. They claim 40,000 volts, but is that a realistic rating, and what do the OE coils produce. Personally I've never had an issue with the OE coils, and there are mods such as the solid copper wire for spark blowout such as the one @Maisonvi did a write up for. This thread is mostly out of curiosity... anyone else ever heard of these?
