I was wondering how to get rid of this? I am guessing replace the wires. I was also wondering what causes it. Any help is appreciated. Thanks, Michael

 

car has bbk shorties on it. The plugs are wired so close the block its not even funny. I am incredibly pissed off since the damn wire doing it has a taylor fire sleeve on it and header wrap on the header. Help me out guys. -Thanks, Michael

 

Usually caused by a brake down in the insulation or wire damage. But can be from to much plug gap or missing electrode.
Check plug, replace wire.

 

They do sell wire sets that go "over the top" instead of under the headers.
