About This 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 (Su itable 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 Overview Brand : CNRAQR Color : with Spark Plug Tester Manufacturer : CNRAQR Show more
