do the ngk colder plug.. its fine with the stock tune. |
I don't think that would be my recommendation actually, and I just installed NGK 97506 (1 step colder) and I'm MHD Stg 1...seems our N55's are pretty particular about their plugs.
I first tried the 97506 on their stock gap (~.03) and got some misfires and went into limp mode. I re-gapped to ~.023 and now seems to be running smooth, but my logs still aren't as clean as before the new plugs. If I were to do it all over again I'd just go with stock bosch plugs, they're plenty fine up to anything on stock turbo.
