Spark Plug GAP!
.032 (In thousandths of an inch)
Caution! Gap is not adjustable on certain plug brands
In addition if you buy the E3 Spark plug you don't need to ajust the gap, and you get triple the spark.
Don't try to adjust the gap, if you don't know how to, or if you are just doing it to feel like a mechanic. K.I.S.S. - Keep It Simple Stupid.
