Iridium Plugs

[ZoomThis]

I am wondering if purchasing new iridium plugs are worth it. If so, NGK or Denso?

Need MP5 help here!!!

I bought them from Protege5Online. I can't say they do a whole lot, though my mechanic swears they're "good for four horsepower". He's a family friend so I won't argue (openly) about that claim...

...where in Wisconsin are you located, just curious. I'm an Illinoisan myself.

I've asked the question before, do some search, you'll see the answers aren't in favor of anything but regular plugs...

I live in Butler,WI. Butler is the northern suburbs of Milwaukee. About a 45minute drive to the Illinois border (my speed).

Zoomthis, let me give you a quote from another post of mine:

One thing to keep in mind about all "performance" spark plug designs is that no plug can magically create horsepower out of thin air or add horsepower that wasn't there in the first place. But improved ignition reliability can minimize horsepower losses caused by misfires. That's why some plug manufacturers claim their spark plugs improve power. The gains come from power that was being lost to misfires.

And here's the thread, there's some interesting stuff about "performance" plugs.
