Alright guys,
I received my Sparkco wires yesterday, and from what I can tell, here are the Changes:
1. The boot design is "much" beefier, meaning a much thicker/harder circluar boot
2. On the old boots, if you looked inside at the connector, the metal fittings where of poor quality, hence connection failure, plus I couldn't even push them on the plug with ease on the old ones,...but the new ones had a much improved metal fitting connection and fit like a glove the first time
3. I got no dielectric grease nor instructions directing me to my local mechanic for installation..LOL!
4. So far didn't break upon removal
5. Didn't get reimbursed on shipping, but I can live with that if the wires function properly
6. I guess, overall, there is a visual quality difference and the damn wires seem to be heavier, probably indicating a stronger tougher boot connection.
7. Will I buy from them again?....yes.......Was customer satisfaction met?.........yes...........Was product revised to be better?..........as far as I can tell, yes
Peace!
