Heat Range 6 sparkplugs?

[HellsBells]

Hi all,

I ran the NGK 7554's on my car, which are heat range 7. I'm upping up the boost and power and am wondering if NGK makes a colder plug than the 7554? Or if any other manufacturer has plugs in heat range 6 -- they have to be for the newer heads though.

Thanks!

Just an FYI on NGK spark plugs...the higher the number the colder the plug. And I don't think anyone but brisk has a plug 2 heat ranges colder than stock. Brisk part#XOR12YS-1
