Clean your oem plug cap components (photos here in the forum), snip wires back to clean copper, apply di-electric grease at all contact points and you will have a much better system...at no cost.Hello , I made the assumption that the cops had been purchased with the plugs / mini loom as part of the kit and not just purchased the cops.
The plug / loom can be purchased separately if required . The sets I have seen are advertised on EBAY UK but are manufactured in the USA. His EBAY name is gsxr123007 and he is advertising sets with and without the resistors.
