0:05: Have you guys tested out the slanted ground non-projected NGK r2558e-9 plugs for B9? I know it won’t help injector issues, but I am hoping it stops the grounds from melting/breaking off. Trying 810 today
2:01: I’ve seen a lot of B9 RS/S cars having issues with plugs. They are having to be replaced as early as 5k-8k miles. From what I hear, it’s an issue with the cars running lean. Have you guys looked into this to see if the tunes are creating these failures?
4:17: Are the failures happening more often on E? Or pump gas too? Or not enough data?
