• COMPARE 2 SPARK PLUGS AT ONCE – Dual-hole testing lets you check two spark plugs simultaneously for a quick side-by-side comparison. Test a new and used plug, or compare plugs from different cylinders, to help identify inconsistent ignition performance without testing each plug separately
• SIMULATE ENGINE RPM FOR MORE INFORMATIVE TESTING – Adjustable operating frequency simulates different engine-speed conditions, allowing you to observe spark performance as the testing frequency changes. This provides a more practical way to evaluate spark behavior than a simple static spark check
• SEE SPARK PERFORMANCE IN REAL TIME – The transparent viewing area makes the spark easy to observe during testing, while the indicator light provides an intuitive visual reference for test status. Quickly spot weak, intermittent, or inconsistent spark conditions and narrow down potential ignition-system issues
• PROTECTIVE COVER FOR CONTROLLED TESTING – The enclosed test area helps contain sparks during operation while allowing clear visual observation. Designed with a protective cover for added separation from the testing area; always keep the cover closed and follow the included safety instructions during use
• BUILT FOR GARAGES, SHOPS & DIY USERS – Designed for 12V gasoline-engine spark plug testing across many automotive and motorcycle applications. Straightforward controls and plug-and-test operation make it suitable for professional technicians, repair shops, hobbyists, and home garages
• ⚠️ Note: Not compatible with very short spark plugs. Please check spark plug size before purchase. For compatibility questions, contact us at [email protected]
