Hi All,
Was just wondering if all of the stuff spark plug manufacturers pump out about their "premium ranges" was true?
EG Bosch Super4 plugs - Are they really going to do what they say, IE improve fuel efficiency etc? Considering we arn't talking performance cars here...
Just wondered what people thought!
