Compare Up to Five Spark Plugs Side by Side on the Bench
The SPT360 fires one known-good reference plug and up to four removed test plugs at the same simulated speed, so differences in spark continuity are easy to see through the transparent cover. It compares spark behavior in air, not under cylinder pressure or load.
- 1 bougie de référence + 4 bougies à tester
- Réglage de 200–9000 rpm
- Affichage numérique rétroéclairé
- Supports de bougies réglables en hauteur
- 110 V / 220 V Input
Key Features
-
Comparaison avec une référence
Put a standard plug in the reference socket and the plugs under test in the other four for a clearer judgment.
-
Régime simulé réglable
Set the firing rate with the RPM + and − buttons and read it on the backlit LCD. The setting is a bench firing rate, not real engine speed.
-
Compatibilité avec les bougies longues
Adjustable socket height accepts longer automotive and motorcycle spark plugs.
-
Allumage en enceinte fermée
The transparent protective cover keeps high-voltage sparks enclosed while all five positions stay visible.

Good to Know
Attention
- Plug voltage can reach tens of thousands of volts during operation. Never run the tester with the cover open and do not touch the plugs.
- Turn the power off before inserting or removing spark plugs.
- Results show spark behavior in air; confirm any suspected fault with the applicable vehicle procedure.
Entretien
- Use and store the tester in a dry, ventilated place.
- Check and tighten loose parts regularly, and replace aging wires or worn parts during maintenance.
