  • Q:

    Overall, the product comparison chart needs a boost in the spark plug section. Two features I was looking for: 1. does it have pre-specified gap and if so 2. what is the gap.

    In reviewing the answers for this product, two answers were given for the pre-gapped size 0.044 and 0.045. Please confirm which it is.
    THanks,
