Product Feature & Functions
1. Step 1, clip the clamp onto the engine. Step 2, put the other end into the spark plug wire. Step 3, read the length on the spark through the small window. The longer the spark gap is, the stronger the coil will be.
2. Another way to judge whether it is working properly by observing the spark's color and jumping pattern to check the coil's condition. A normal spark appears blue-purple with steady jumps, while non-normal sparks (yellow/red and inconsistent) may indicate an issue. Simple and effective for quick diagnostics
3. Spark plug tester has a compact size of 4.55 inches in length, 0.93 inches in width. With a 20.08-inch wire included, its lightweight design makes it easy to carry and store for on-the-go diagnostics or garage use
