CNRAQR Spark Plug Tester & Spark Plug Gap Tool Kit 0 to 6000RPM with Double Hole Spark Plug Adjustable Gap Tool with Feeler Gauge Ignition Coil Tester for 12V Gasoline Vehicles Spark Plug Socket

CNRAQR Spark Plug Tester & Spark Plug Gap Tool Kit 0 to 6000RPM with Double Hole Spark Plug Adjustable Gap Tool with Feeler Gauge Ignition Coil Tester for 12V Gasoline Vehicles Spark Plug Socket

• All-in-One Diagnostic & Adjustment: Combines a dual-hole spark plug tester (compatible with spark plugs with insulator diameters under 13mm) and a universal gap tool (Suitable for 10mm, 12mm, 14mm, 16mm spark plugs) for a complete solution to test spark plug performance and adjust electrode gaps
• Easy to Use: Effortlessly test two spark plugs side-by-side, while the bright indicator lights and adjustable RPM knob (0-6000 RPM adjustable) provide instant visual feedback on spark intensity. No technical expertise needed—simply plug in, adjust the frequency, and diagnose misfires, weak ignition, or fuel inefficiency in minutes
• Universal Compatibility: Test 99% of 12V gasoline engines, including cars, trucks, ATVs, and 12V gasoline engines, with the ABS heat-resistant tester (12mm socket) and gap tool. Adjust plugs for turbocharged engines, high-flow intakes, or performance upgrades, ensuring optimal spark plug health
• Real-Time Engine Simulation & Spring-Back Compensation: Simulate engine load conditions to observe spark performance under stress, mimicking real-world driving. The gap tool accounts for electrode spring-back for accurate adjustments,achieving target gaps
• Durable & Heat-Resistant: Built with industrial-grade ABS, the tester withstands high temperatures and repeated use. The aluminum spark plugs gap tool can make it easy to adjust plugs without damage—even in compact cars or motorcycles
