What is the correct grade plug for my 88 300TE M103? Haynes quote a Champion S10YCC - my local shop have given me NGK BF6EP on one occasion and BF5EP on another. Euro Car Parts quote Beru or Bosch H8DCO. Which NGK grade is correct and will it cause a problem if I use the other? Are the Champion and Beru grades compatible?
Many thanks
