Got my massive speed wires and copper cores on today. Maybe its because my factory plugs had 76,000 km on them but wow I loved the test drive after. Also could be that I haven't given it gas like that in a while lol.
The massive wires seem like good quality plus have a lifetime warranty for only $40. Only complaint is the #4 wire is a about a half inch too long so it wants to bend a bit too much at the coil.
ps... I'm pretty sure they are the exact same as the focussport ones..
Wish it is as fast as it sounds...
