Does anyone have any experience with these? I have just ordered some for my Max and Bike (late night e-bay shopping)I don't really see much talk on them here. Any users?

 

I'd like to give those a try too when it's time for my plug change.
From what I've read, for some reason most of the guys on here stick with the NGK plugs when they need to replace theirs.

 

I'll let you know how they turn out..should be in within a week or two.

 

I've installed mine about 6 weeks ago. loved it and it gives a little more power for the bucks!

 

I have them in my 2k. I put them in at about 52K miles on the car. I definitely noticed that the engine was quieter, smoother, and a bit more pull. But I really think there isn't much difference between iridium, platinum, and copper. One will see more of a difference if they are boosted, or nitrous. Keep in mind that the iridium only last 30k miles. Sooo...that's equivalent to a copper plug at about 8 times the cost. Just FYI...I'm chaning to copper on the next go around.
