Adjustable Ignition Spark Tester with 0–40 kV Scale Ground Clip and 19.7-Inch Cable – Ecocstm 1 or 2 Pack

An adjustable ignition spark tester lets technicians compare spark length while checking automotive and small-engine coils. Ecocstm uses a pitch-adjustment knob and a high-visibility window marked from 0 to 40 kV, helping users observe the discharge under different test gaps.

A rubber-coated 19.7-inch ground lead, alligator clip and spring provide a stable connection. Clip the lead to engine ground, connect the opposite end to the plug wire and observe the spark through the window according to safe service procedures. The tester measures 4.5 inches long and is sold singly or as a two-pack.
