SPARK PLUGS!!!! ARE THEY A HYPE OR ARE THEY FOR REAL?

[jimberg]

I hate to disagree with you Unit, but platinum is much less likely to miss, that's why they use it. The benefit of platinum plugs is that they last much longer and spark much more reliably at lower voltages. The problem is that since the voltage is much lower, the spark is much colder.

We performance oriented type people change our plugs often enough that we could care less if our plugs last for 100k miles, but we also want a nice hot spark to go with our high performance coils. Copper core plugs give us that.
