well i saw a car with taylor spark plug wires and wow, were they big....i researched and found that they are $150+ for a set....is it worth the $150+ on a semi moded car??
I have the 10.5 mm Taylor Thunderbolts. They are a nice quality wire...but I also have screamon demon coil packs. So on a stock car you won't notice a real benefit from a fatter plug wire. But they do look impressive!
