A friend has the super comp headers on his car & the tube goes directly in front of the # 3 spark plug , we have replaced that ign wire at least ten times as it burns through even with double insulation on it , I tried using Hemi wires with the bakelite extension but that burns through as well , we will have to pull the engine , remove the header & rework it , cut & re angle the tube or cut a c into the tube & reweld it to get some clearance , cutting costs always costs you more $$ in the long run , Ign wires are not cheap & the time to pull the engine & rework the header will probably cost more then the TTi would initially , the problems is now we have to pull the engine anyway so figure at least 6 hrs in & out & fluids & then the cost to fix a crap header .
