Great plugs, I felt the improved acceleration right away. Only have a few hundred miles on them, but I like what I see and feel so far.

The Flame Thrower HC coil and the Flame Thrower ignition module for my stock application with the Ford factory 2.3 liter 4 cylinder multi-fuel injected turbocharged ran to lean, missed and cutout. For a modified application of my engine needing a hotter spark it would be great. The factory coil after researching is 40,000 volts, so I have ordered the Flame Thrower TFI for Ford ignitions rated at 50,000 volts, Pt.# D3003.
