What would be one step hotter plug than an NGK 4554??

That is the # summit gives for the recommended plug for the Brodix heads.
I want to try one range hotter.

(I've ran that number for a couple years.)

Thanks!!

Stock # 4091 ( R5671A-7 ) would be one step hotter than the #4554.
It looks like the 4091 is the hottest plug in the series. -7 thru -11.
