Has anyone seen much gain from Ignition wires?

 

JBA wires and Zippo improvement over correctly functioning stock ones. They will only solve a voltage drop due to excessive resistance caused over time or actual defective wire and will not "add" any HP. They may feel as if they do but all they are doing is restoring spark lost over time. I actually had a bad wire and rather than fight with dealer over new set (still on warranty) i decided to upgrade to JBA power wires. Blue ones by the way...
