Why you need the spark plug tester:
1. Deteriorating spark plug performance can cause deposits to build up, which can lead to difficulty starting the vehicle
2. Spark plug failure resulting in incomplete engine combustion and abnormal increase in fuel consumption
PRODUCT FEATURES
Blue-Purple Sparks
The spark in the spark plug tester window is blue-violet and the spark is steady and regular, indicating that it can continue to be used.
High Pressure
The inner part of the grounding wire is made of pure copper wire, which can withstand high voltage current and protect your safety.
Adjustable Design
Jump distance can be adjusted from 0 mm-40 mm/0“-1.54” by turning the red knob at the top to improve compatibility.
