Best plugs are iridiums IX?

please help..

keep in mind that the NGK TR6 are colder than normal plugs - designed for highly modified engines. If you are running a mostly stock/lightly modded motor, then the TR55-IX are the ticket.

I voted for the NGK TR6, but, keep in mind that there isn't any one plug that is best for everyone. The TR6 is good for FI applications as the cooler plugs tend to prevent pre-ignition.
