I'm thinking of trying them out on my 2.0 16v. I know they cost a little more than a regular Bosch plug but they claim to provide a most efficient spark that helps with poor fuel/air ratios and rough idle. Does anyone have any experience with them? If they're no good, I will go with Beru Silverstones then.
