go here: sparkplugs.com , enter IK16 into one of the boxes, and it comes up with an order from showing $11.99 per plug.

I got mine from Speed Demons
Kooldino said:So what have we learned?
-mp3's supposedly come with iridiums
-the iridium 16's would be best for most of us
-Linux knows martial arts
what we need:
-dyno with stock plugs vs iridium plugs
-a place we can get the new plugs online for a good price

Thanks dude!
Woody said:I installed denso iridium plugs yesterday. The other mods I have are AEM Short Ram intake, and Mazda Sport exhaust. Anyway, geez, maybe its in my head but I feel there is definately more responsiveness to the engine, and noticiably more zap as well - more than I expected.
Has anyone else tried these with similiar mods? Is it all in my head?
