Brisk RR15YS plugs

[georgeschuer]

I had given up on the i2 for my 2013 SHO. Install a new set of SP534's gapped at .028 and runs great for two days then just stumbles all over itself at anything over half throttle. Most of the time it would post a code and barely limp off to the side of the road where a shut down and restart is required to get it to run correctly again until the next time I get on the gas hard. I went through a lot of plugs before I gave up. I was reading about Brisk RR15YS silver tipped plugs and they seem to work pretty well. Thought I might try one last time but I would love to hear how they worked from anyone who has tried.
