I've ran these for a few years stage 2 e85, with absolutely no issue at all. The last year and a half I've been running a bigger turbo, powermax 2260 and have had zero issues
Pros: no issues at all
Been running them for the last year on EQT stg 1 91 and e30 with no issue.
Pros: no issue
Gonna do brisk silver with 4C coils unless someone has any advice on Brisk Silvers being bad. Was gonna try them out over the NGK Laser Iridium
Cons: brisk silvers being bad
Skip them, they are junk and a waste of money.
Get a good single platinum plug like the Denso 4511.
Pros: good platinum plug
Cons: junk, waste of money
