Daniel,
Yes, My Magnecors set is blue also. Since my car itself is red, I did think about the KV 85( 8.5 mm) cable which is, of course, red but since I don't have a competition ignition system and the car isn't turbocharged, I settled for the blue Electrosports 80.
I was also concerned as to whether the thicker cable and bigger plug lead tops would fit under the central cam cover which I have fitted to my car
So far I am very pleased with the set
Best wishes,
G
