Which Spark plug?

[MikesFixedRoof]

Just out of curiosity, have any of you tried silver plugs? Silver is supposed to conduct electricity better than almost any other metal, but I really do not know if that equates into better spark.

Please correct me if i am wrong, just figured I would ask.

If that's the case, then copper plugs make a lot of sense. I've never heard of silver plugs though. Has anyone else?

the only "silver tipped" plug i can think of is some new ones i saw at kragen, the brand name illudes me at the moment, nut the price is permanently burned into my retna, 25 bucks... EACH!!!!! yyyeeeaaaaa, i have had the bosch plus4 platnum in mine since i put the new motor in it, got around 35k on them, and i dont think i have had any problems resulting from those.

I have had numerous problem with bosch in Imports. Haven't tried in my supra... but with bosch +4 still only one prong will ignite instead of all four (closest one to the center electrode). NGK or DENSO... I'm running the NGK BCPR6EGP (.032 gap) in mine with great results at 10psi. I will be getting my hands on some BCPR7ES soon.
