I just ordered some NGK Iridium plugs. You can probably find them online somewhere. I know parts america has them for like $10.50/plug. I got four off ebay for a little over $20. THe part number is BKR5E-IX.

NGK/Denso are real nice. The iridiums have a much larger spark compared to platinum and last longer as well. That's what you get for paying so much for spark plugs

Since you've got a KA you should be more than happy with iridium plugs. Anyone who is running considerable boost and hp should use copper, as you can get them in steps colder which is engine-friendly. Plus, you'll probably foul a few plugs until you find the sweet spot and who wants to spend $40 per set of plugs.

You can get all sparkplugs in a variety of heatranges. I'm running NGK Iridiums 2 steps colder.
Smaller tips on the iridium means that the electrons build up in a smaller area, using less voltage to create the same sized spark, or a larger spark using the same voltage. Kinda like a poor mans ignition system.

I use the basic NGK copper plugs myself, and having switched from bosch platinum +4s, I like the slight difference in how the car runs now...

Huh, that's interesting. I always thought the iridiums were at one set heat range and the only plugs with varying ranges were copper and platinum. I'll remember that for future reference.

I just ordered NGK Iridium's from pdm-racing.com for $5.00 a plug, parts america looks like a ripoff now :-P
