Most people run Magnecor. I use KV85, Bens are the same. At the end of the day plugs and leads either work or they dont, there arent really any performance gains to be had, only lost through crappy gear. The standard Bougicord leads on a valver are very good leads so only worth replacing if theres anything physically wrong with them or you dont like the colour or something. The Bougicord and Magnecor leads are made in a very similar way. Other performance leads you find out there arent made the same.
BTW I had Super 4s for a year or so. No problems. They fired the cylinders fine under every circumstance I encountered, road use, hot use, cold use, track use, quarter miling on nitrous. All you can expect plugs to do is fire, so under that criterium, I thought they were bloody good. Obviously Ben and Chris must have some reason why they didnt like them. Likewise Champion EON1 were fine as well.
