eviljim Posted June 28, 2014 Report Share Posted June 28, 2014 So NGK. Tells me to use a BP7ES. Went to get a new one from local shop and they did not have one. I can get one online I am sure but I was thinking could I just put in a B7ES OR A BR7ES. Quote Link to comment Share on other sites More sharing options...
lineaway Posted June 29, 2014 Report Share Posted June 29, 2014 The BP stands for projected reach. Its longer. You can use a bp5es- bp8es. I always ran a BP5es , but we are at high elevation. Quote Link to comment Share on other sites More sharing options...
