How Good are these?
Compared to standard plugs

• Long life 5 to 10 times
• 10-20% less voltage required to fire
• Less likely to foul under poor operating conditions
• Easier starting
• Will fire inconsistent mixtures

Sound too good to be true?

The downside is they cost 5 times as much as standard plugs
