[Supras] Colder plugs, when do yall use them?

[Steve Michael]

6 is the stocker range from NGK, 7 is one cooler.

Both Dave K. and I run the Iridiums in the one cooler range:

BCPR7EIX (stock #5690)

LOVE them here in AZ. I also run a tuned (ala Lexus/Hall) set-up with bench-flowed 440's (to 455 ea or better),
and a solid tune by Dynocomp with my S-AFC. I pulled them after 2 years and they looked fabulous.

Go to www.sparkplugs.com or call them at 888-800-9629
The AZ Supras used to get a discount, but I can't remember the code for it.
Call the 8888# and ask someone about a MkIII discount.
Even without the discount, shipped price for all 6 is ~$50.

Steve in AZ...90T for Me!

I was thinking 7 was the stock range but the 2330's are BCP6RE, is the 6
designation not the heat range? Also, I've noticed I get some plugs
(NGK) that have a silver base and some are gold (cadmium?) I try to
match them, just wondering if anyone else noticed that?

Anyone else have the number written near the phone so you can call and
see who
