Question

What is the correct range of gap size in the millimeter of a spark plug?

(a) 0.35-0.45

(b) 0.6-0.1

(c) 1-2

(d) 2-4

Answer 1

Correct choice is (b) 0.6-0.1

Easy explanation: The correct spark plug gap size is specified by the manufacturers varies in general from 0.6 to 1millimeter. For the new spark plug, the gap is generally 0.6 millimeters, but with use it is increased, thus requiring higher voltage for the spark to jump across it.
