Is anyone using NGK Iridium Spark Plugs in thier C 3 ???

[SwaveDave]

If so, how do u like them ? Any noticeable difference by using them ? Where did you buy yours ?

Thanks, dave.

Those are great plugs for certain applications. Don't know if they would do much different in the big block.


I have used them on two stroke engines, motor cycle engines, boats, and imports with great results.


I see no reason why they would not work.


I sure hope to see you at Sharkfest this year. We can compare torque and hsp notes.

I'm using NGK plugs with Vortec heads. I'm not sure if they are Iridium but I really like them.
